DA14 Outriders COULD Have Fallen On Northern Hemisphere

For the past couple of weeks, since Asteroid DA14’s close approach to Earth on 15 February, and the fireball over Chelyabinsk on the same day (about 3:30 am UT), like many people I’ve been wondering if the two events were related – particularly since there were other fireballs spotted around that time (e.g. the one seen over the west coast of the USA the same evening).

The experts, however, seem to have been unanimous in denying any connection. Their reconstruction of the Chelyabinsk fireball’s orbit prior to its impact places it in a quite different orbit than DA14. It was, they say, just sheer luck that two different asteroids, coming from quite different directions, happened to arrive at more or less exactly the same time. In addition, they have pointed out that DA14 was approaching the Earth from below the south pole, and so given that the Chelyabinsk is at latitude 55N°, it was next to impossible for anything coming from that direction to land on Chelyabinsk.

I wasn’t so sure, myself. Four of five years ago, purely as a matter of interest, I wrote a clunky little computer simulation model of the solar system, using planet vectors (position and velocity) from JPL’s Horizons website. I also included a clunky little model of the Earth, complete with outlines of its continents, spinning on its axis.

I say the model is a bit clunky because it’s riddled with divide-by-zero errors which I never got round to cleaning up. Also, the Earth goes round the Sun a day quicker than it should do. In short: it’s not very accurate.

But I thought it might be accurate enough to allow me to find out whether rocks in a fragment cloud around DA14 might have fallen in the Earth’s northern hemisphere. So I got hold of DA14’s orbital vectors for a few weeks before the 15 February encounter, and added them into my solar system model, and found that in my model DA14’s closest approach was two minutes before its recorded closest approach, and at a distance of about 33,800 km from the Earth, about 250 km less than its recorded distance. Which I thought was quite good.

I then created a halo of fragments around DA14, travelling at the same velocity, and looked for ones which hit the Earth. And I found plenty. More or less all the halo fragments that hit the Earth landed in the southern hemisphere, as expected. But a few of them curved round the side of the Earth, and swung in towards it. I concentrated on these ones.

And today I managed to find one (which I’ve named Halo10120) which came down in Mongolia a bit south of Irkutsk, at 46°N. Here’s a screenshot of the Earth, with the fragment (which weighed one metric ton) passing over the Earth at about 12.5 km/s and just grazing its surface (the bit where the red track turns green) before heading back out into space:


This view of the transparent Earth is looking down onto the plane of the ecliptic (the path swept out by the Earth as it travels around the Sun). The continents in the upper half are outlined in black, and on the lower half in grey. The north and south poles are marked with crosses. Chelyabinsk is a dot on the map north of the Aral Sea, and the Sun (way off in the bottom right of the picture) is just rising there. Halo10120 comes up from right to left, more or less from where the Sun is.

Here’s another larger scale and smaller scale view.

As you can see, this impact site isn’t very far from Chelyabinsk, and it’s at almost exactly the same time as the Chelyabinsk event. And the path of the fragment is from southeast to northwest (the Chelyabinsk fireball was rather more east to west than this).

This isn’t a complete reconstruction of the Chelyabinsk fireball, but I think it makes a pretty good case that it could well have been a fragment of DA14.

I haven’t yet managed to find a fragment that got as far north as latitude 55°N, but in one or two cases I’ve managed to reach 49°N. So 55°N is far from impossible.

One of the puzzles of this matter is that all the fireball reports around that time were in the northern hemisphere, and none at all came from the southern hemisphere. And yet, by my own estimate, something like 95% – 99% of DA14 fragments would have fallen in the southern hemisphere of the Earth.  Surely, if there was a cloud of rock fragments around DA14, there would have been hundreds of reports of meteor impacts in the southern hemisphere?

But the explanation for this may well be that all of the northern hemisphere sightings were of fireballs that skimmed the atmosphere, and travelled through it at quite high altitudes (about 50 km) for quite long distances, and which would have been visible from a long way away for quite a long time (several tens of seconds). Furthermore, most of the world’s population lives in the northern hemisphere of the Earth, and so there would have been more eyes to see such events.

By contrast, the fragments that hit the southern hemisphere tended to come down more or less vertically, punching through the top 50 km of the Earth’s atmosphere in 4 seconds while travelling at 12.5 km/s, and transferring most of their energy to the Earth, rather than to its atmosphere.

Southern hemisphere DA14 halo fragments would have been experienced as a brief flash, perhaps accompanied by a sound of thunder, and maybe an earth tremor as well. They wouldn’t have been seen by many people – mostly because the Earth’s southern hemisphere isn’t well inhabited.

What does it all add up to? Most likely that almost all the fireballs seen around the world around 15 February 2013 were DA14 halo fragments.

And that’s a bit worrying. The impact of the Chelyabinsk fireball has been estimated as several multiples of the Hiroshima bomb, even if it only injured about 2000 people on the ground.

We live in a world in which it is believed that the greatest threat to human health and longevity is caused by smoking, and drinking, and eating too much.

I think there are maybe some far greater threats around.

    Riot fears as cigarettes set to be banned from prisons in England and Wales to stop passive smoking compensation claims from officers

    “Jail bosses had hoped to ban smoking by January but the deadline has been pushed back after a planned pilot at jails including at Exeter, Devon was postponed, but they are confident of introducing it within the next 24 months.

    It is accepted the ban must happen for health and safety reasons and to avoid officers seeking compensation claiming to be victims of passive smoking.”

    But the date of guilty knowledge has passed!

    Any prison officer who gets any disease in later life that has ever been designated as “smoking-related” – and that’s pretty much everything anyone is capable of suffering from – and worked in prisons between 2004 and whenever smoking is banned is in line for a payout.

    What’s sauce for the goose is sauce for the gander and the Government may in time have cause to regret that they were ever signed up to this –

    Secondhand Smoke: The FCTC Commitments
    ‘Parties recognize that scientific evidence has unequivocally established that exposure to tobacco smoke causes death, disease and disability’.

    Who decided on the date of this guilty knowledge?

    “In a legal opinion obtained by ASH, J. Melville Williams QC suggests that not only has the date of guilty knowledge passed for employers, but also for the Health & Safety Executive and Commission.”

    Back in 1998, the Scientific Committee on Tobacco and Health (SCOTH) estimated the increased risk to non-smokers of lung cancer from ETS at 24%; the excess risk of heart disease in non-smokers compared with those not exposed was 23%, and important risks to the children of smokers were identified [3].

    These statistics were sufficiently compelling for Action on Smoking and Health (ASH), the anti-smoking lobbying group, to write to leading hospitality industry employers suggesting that the date of ‘guilty knowledge’ had now been passed and consequently employers were vulnerable to serious legal risks if they continued to knowingly expose employees and others to second-hand smoke.”
    http: //occmed.oxfordjournals.org/content/55/8/583.full

    ‘Parties recognize that scientific evidence has unequivocally established that exposure to tobacco smoke causes death, disease and disability’.

    “to avoid officers seeking compensation claiming to be victims of passive smoking.”

    But in fairness I would imagine that the Government can only be held liable under the 1974 health and Safety Act, from the moment they signed up to that section of the FCTC and deprived themselves of all possible defence against such claims.

    • harleyrider1978 says:

      Kind of hard to claim harm when none exists as in evidence! When Lord Nimo tossed out the LC case for no evidence that ASH could produce that doesnt leave any wiggle room for their charge of officers trying to claim harm from passive smoke,even in the most extreme case. Any Doctor that proffers and opinion to that effect would be summerily charged with FRAUD and lying under oath!

      This pretty well destroys the Myth of second hand smoke:


      Lungs from pack-a-day smokers safe for transplant, study finds.

      By JoNel Aleccia, Staff Writer, NBC News.

      Using lung transplants from heavy smokers may sound like a cruel joke, but a new study finds that organs taken from people who puffed a pack a day for more than 20 years are likely safe.

      What’s more, the analysis of lung transplant data from the U.S. between 2005 and 2011 confirms what transplant experts say they already know: For some patients on a crowded organ waiting list, lungs from smokers are better than none.

      “I think people are grateful just to have a shot at getting lungs,” said Dr. Sharven Taghavi, a cardiovascular surgical resident at Temple University Hospital in Philadelphia, who led the new study………………………

      Ive done the math here and this is how it works out with second ahnd smoke and people inhaling it!

      The 16 cities study conducted by the U.S. DEPT OF ENERGY and later by Oakridge National laboratories discovered:

      Cigarette smoke, bartenders annual exposure to smoke rises, at most, to the equivalent of 6 cigarettes/year.


      A bartender would have to work in second hand smoke for 2433 years to get an equivalent dose.

      Then the average non-smoker in a ventilated restaurant for an hour would have to go back and forth each day for 119,000 years to get an equivalent 20 years of smoking a pack a day! Pretty well impossible ehh!


      According to independent Public and Health Policy Research group, Littlewood & Fennel of Austin, Tx, on the subject of secondhand smoke……..

      They did the figures for what it takes to meet all of OSHA’S minimum PEL’S on shs/ets…….Did it ever set the debate on fire.

      They concluded that:

      All this is in a small sealed room 9×20 and must occur in ONE HOUR.

      For Benzo[a]pyrene, 222,000 cigarettes.

      “For Acetone, 118,000 cigarettes.

      “Toluene would require 50,000 packs of simultaneously smoldering cigarettes.

      Acetaldehyde or Hydrazine, more than 14,000 smokers would need to light up.

      “For Hydroquinone, “only” 1250 cigarettes.

      For arsenic 2 million 500,000 smokers at one time.

      The same number of cigarettes required for the other so called chemicals in shs/ets will have the same outcomes.

      So, OSHA finally makes a statement on shs/ets :

      Field studies of environmental tobacco smoke indicate that under normal conditions, the components in tobacco smoke are diluted below existing Permissible Exposure Levels (PELS.) as referenced in the Air Contaminant Standard (29 CFR 1910.1000)…It would be very rare to find a workplace with so much smoking that any individual PEL would be exceeded.” -Letter From Greg Watchman, Acting Sec’y, OSHA.

      • Rose says:

        But Harley, after the government have agreed that “‘Parties recognize that scientific evidence has unequivocally established that exposure to tobacco smoke causes death, disease and disability’.”
        If public workers were to claim compensation for these alleged smoking related diseases from exposure on government premises, how can they do anything but settle out of court?
        To even try to defend themselves they would have to admit that the whole thing was untrue.

        Do you see my point?

      • beobrigitte says:

        The Daily Mail’s anti-smokers are getting carried away again; perhaps UKIP’s rise has something to do with it?
        Just when you think that the anti-smokers have reached the last level of idiocy, they prove they can create a new one
        “to avoid officers seeking compensation claiming to be victims of passive smoking.”
        Aren’t most prison officers smokers? And, from what we get to read/hear, SECOND HAND SMOKE is the least of prison officers’ problems.

        Harley did already pointy out:

        Parties recognize that scientific evidence has unequivocally established that exposure to tobacco smoke causes death, disease and disability’.

        Let’s remove ALL tobacco control financed studies for “scientific evidence” and see what is left.

        Schuman’s Expert Witnesses Testify in Secondhand Smoke Trial

        The plaintiff’s expert witnesses spoke up on day three of David Schuman’s case against his housing cooperative, Greenbelt Homes, Inc. (GHI), for its failure to prohibit the nuisance created by his townhome neighbors, the Popovics’, secondhand smoke.

        Courtroom and Plaintiff’s Townhome Register Similar Carcinogen Levels

        But, an incident from Repace’s testimony Thursday came back into play Friday during cross examination. Goecke pointed out that on Thursday, while demonstrating the carcinogen monitor, Repace had measured the concentration of carcinogens in the court room — which is in a smoke-free building — and the amount he recorded there was similar to what Repace had reported recording in Schuman’s townhome in July of 2011.


        As you can see even in a smokefree courtroom the same so called levels were read in Schumans own Kitchen in his house! The so called scientist was none other than a fellow prohibitionist and JUNK SCIENTIST,Tornado Repace!

        Talk about being laughed out of court……………….btw these prohibitionists create whats called ”risk assesment studies” Purely fictional and nothing more than statistical magic to create fear and bigotry against smokers!

        • harleyrider1978 says:

          Why did the nazis choose continine as their bio-marker of exposure! Simply they couldnt measure tobacco smoke chemicals in the air as the natural air contains the same levels. Itd have to be a sealed off room to actually measure those chemicals accurately. In the above Old REPACE put his Carcinogen meter in the plaintiffs kitchen where he knew he could measure what should have been higher levels due to the cooking……….A sly trick that didnt pan out!

    Actually, I would think that such a lawsuit might be a blessing in disguise. A good defense legal team should be able to present the real facts on SHS. This, I think would be the first time that the lies and junk science would really be publically exposed. I would love to hear other peoples takes on this.

    • Rose says:

      The official explanation of ETS statistics

      “Mr Bloom wanted to know, in the light of the figure and bans: “could the Commission please name three or four people who have died from Environmental Tobacco Smoke (ETS) within the EU in the last two years?”

      Here is the answer on the 79,000 deaths every year figure from Androulla Vassiliou, the European Health Commissioner.

      “These estimates are based on the international evidence on the level of risk posed by exposure to ETS and the estimated proportion of the population exposed rather than individual cases of deaths due to passive smoking.”

      “The nature of the epidemiological evidence on all risk factors, be they chemical or other, is such that it does not allow to identify the victims at individual level but only populations.”

      • Rose says:

        Oops that should have had another link also explaining the “manifestly unfounded” Labate case as well as Geoffrey Bloom’s question.

        • nisakiman says:

          The problem is that all these facts become academic in the face of popular consciousness. It makes not one jot of difference whether or not the science is on our side. They have mobilised popular opinion via an intense propaganda campaign, so now, for all intents and purposes, ‘second-hand smoke’ kills hundreds of thousands a year. The lack of bodies is an irrelevance.

          I am currently doing a job for a client, a young and intelligent woman with two small children. She is avowedly anti-smoking, and is convinced that a whiff of SHS is lethal, although to be fair to her, also pragmatic about it. (She’s Greek / English and lives in Greece, so I guess has no choice but to be pragmatic). In my last email to her, I sent her a couple of links to the results to the Ernst – Kabatt study and the (quickly buried) WHO study. The email I got in return completely rejected the notion that there was no real danger from SHS. She refused to accept that her indoctrination was flawed, even in the face of evidence.

          And that is what we face. There is no talking to people like that. You are undermining their basic belief structures, and they will close their minds to any evidence you might produce.

          As far as she, and millions more like her are concerned, SHS is a killer and smoking bans are a way to ameliorate that damage. End of.

      That’s why they probably wouldn’t allow it to get as far as court, Gimper

  5. Rose says:

    “The nature of the epidemiological evidence on all risk factors, be they chemical or other, is such that it does not allow to identify the victims at individual level but only populations.”

    The answer from the European Health Commissioner seems very similar to paragraph 9 from our own HSE

    “The evidential link between individual circumstances of exposure to risk in exempted premises will be hard to establish. In essence, HSE cannot produce epidemiological evidence to link levels of exposure to SHS to the raised risk of contracting specific diseases and it is therefore difficult to prove health-related breaches of the Health and Safety at Work Act”

      Epidemiologists Vote to Keep Doing Junk Science
      Epidemiologists Vote to Keep Doing Junk Science

      Epidemiology Monitor (October 1997)

      An estimated 300 attendees a recent meeting of the American College of
      Epidemiology voted approximately 2 to 1 to keep doing junk science!

      Specifically, the attending epidemiologists voted against a motion
      proposed in an Oxford-style debate that “risk factor” epidemiology is
      placing the field of epidemiology at risk of losing its credibility.

      Risk factor epidemiology focuses on specific cause-and-effect
      relationships–like heavy coffee drinking increases heart attack risk. A
      different approach to epidemiology might take a broader
      perspective–placing heart attack risk in the context of more than just
      one risk factor, including social factors.

      Risk factor epidemiology is nothing more than a perpetual junk science machine.

      But as NIEHS epidemiologist Marilyn Tseng said “It’s hard to be an
      epidemiologist and vote that what most of us are doing is actually harmful
      to epidemiology.”

      But who really cares about what they’re doing to epidemiology. I thought
      it was public health that mattered!

      we have seen the “SELECTIVE” blindness disease that
      Scientist have practiced over the past ten years. Seems the only color they
      see is GREEN BACKS, it’s a very infectious disease that has spread through
      the Scientific community with the same speed that any infectious disease
      would spread. And has affected the T(thinking) Cells as well as sight.

      Seems their eyes see only what their paid to see. To be honest, I feel
      after the Agent Orange Ranch Hand Study, and the Slutz and Nutz Implant
      Study, they have cast a dark shadow over their profession of being anything
      other than traveling professional witnesses for corporate hire with a lack
      of moral concern to their obligation of science and truth.

      The true “Risk Factor” is a question of ; will they ever be able to earn
      back the respect of their profession as an Oath to Science, instead of
      corporate paid witnesses with selective vision?
      Oh, if this seems way harsh, it’s nothing compared to the damage of peoples
      lives that selective blindness has caused!

      The rise of a pseudo-scientific links lobby

      Every day there seems to be a new study making a link between food, chemicals or lifestyle and ill-health. None of them has any link with reality.

    Meteor Strike: Fireball from Space – 4oD – Channel 4

    But you have to wade through half a minute of adverts before you get to the programme.

    • Margo says:

      I saw that programme this evening. No mention of the other fireballs and whether they were connected. It was a lot about scientists gathering up bits of the mereor for analysis, and where in space it came from. I didn’t learn anything new, really, just that there are limitations on what the scientists can see or predict.

  10. beobrigitte says:

    I did watch the channel 4 programme about the “meteor” which struck Chelyabinsk. It wasn’t as informative as I had hoped. The only reason for “missing” this meteor apparently was, that it came from the direction of the sun and with that it could not have been seen. (???) The possibility that this meteor could have been a fragment of DA-14 was not mentioned.
    Nevertheless, the videos did show that it exploded and fragmented. It was assumed that this meteor was knocked from it’s orbit by “something” (?DA-14) which caused ruptures in the stone, leading to fragmentation due the stresses added to the “stone” by our atmosphere. (Some of these fragments were collected and it was found that it was a “stone” (with very little/no metallic content) meteor.)
    The delay inbetween the fragmentation and the following blast of ca. 3 minutes was explained by shock waves travelling at a much slower rate than do sound waves.

    During this programme my mind kept returning to the question: HOW can we miss a meteor coming from the direction of the sun when we can and do monitor the sun’s surface?

  11. Frank Davis says:

    Thanks for the Channel 4 link, Rose.

    There were a couple of new things I learned. Most notably that the meteor had been struck by another meteor. Which is exactly what I would expect of one that came from a fairly dense fragment cloud.

    I thought the ‘coming out of the sun’ thing was a bit thin. I think the reality is that it was too small to be seen, even if it hadn’t come from that direction.

    As for the direction it came in from, they didn’t mention that their calculations would have produced a cone of possible paths, not one single path. And from within that cone it could have come anywhere.

    As Brigitte said, there was next to no mention of all the other fireballs around that time. They treated it as if it was a one-off coincidence. It wasn’t. There were several fireballs. Too many, in my view, to be just a lucky accident.

    Alex Jones 15 feb 2013

    Experts are pondering whether a meteorite shower which caused panic in Russia, injuring over 900 people, devastating buildings and wiping out the cell phone network, is linked to today’s fly-by of DA14, the “city killer” asteroid that NASA has assured will not hit the earth.

    Space experts are divided on whether the meteor is connected to today’s fly-by of asteroid DA14, which will pass within 17,200 miles of the earth’s surface, closer than many orbiting satellites.
    The European Space Agency (ESA) put out a message on its official Twitter account claiming that the meteor shower was not debris from the DA14 asteroid.
    However, Tatiana Bordovitsina, an astronomy professor at Tomsk State University in western Siberia, told RIA Novosti that the meteor, “could have been debris preceding the asteroid.”
    Professor Ian Crawford of Birkbeck University told Sky News that, “it was too early to tell if this incident was connected to the asteroid passing by the earth tonight,” but added that if meteorites were traveling with the asteroid, they would be several hours ahead of it.
    Curtin University asteroid expert Phil Bland told an Australian website, “Is it connected to the flyby? A lot of folks would say “no”. Personally, I’ve always kind of liked the idea that there are streams of asteroid debris – so you can have smaller stuff that precede and trail a bigger object. It seems like an awful big coincidence if it’s not connected.”

    Dr Stephen Lowry, planetary scientist at the University of Kent, doubted the connection but remarked that the meteorite shower was “an incredible conincidence.”
    “If I had to bet, I would say it’s not related. But it’s not unheard of for asteroids to have companion bodies with them,” said Mark Ford of the British and Irish Meteorite Society.

  13. Frank Davis says:


    Having reviewed some of my readings in the EPH, it seems we just need to establish whether or not the orbit of DA14 grazed or intersected with the Chelyabinsk area in the hours prior to the asteroid’s passage. The meteor needs simply to be in the same orbit as the asteroid, for this event to be a confirmation of Tom van Flandern’s Exploded Planet Hypothesis.

    The EPH describes an event which “gave birth” to asteroids and comets in the solar system. Thus, having given them a common origin, van Flandern predicted similarities between asteroids and comets, that the mainstream could/would not countenance for many years. One such was the possibility of atmospheres and outgassing on asteroids. Van Flandern went on to predict that asteroids and comets would have satellites (this has now been abundantly observed in asteroid fly-bys), and that asteroids might have their satellites “land” on their surfaces, after orbital decay (this prediction was verified with observations of Eros).

  14. beobrigitte says:

    and that asteroids might have their satellites “land” on their surfaces, after orbital decay

    I hasten to add that I am NOT an expert; I’m just merely wondering. At what point and more importantly, what would be the cause, of a satellite changing course prior to entering the earth’s atmosphere?
    DA-14 followed it’s predicted course, so it is not very likely that it did hit any of the asteroids. (A tiny course change would become more obvious the further it travels.)
    If DA-14 has not hit any of the asteroids, sending it in direction of earth, what did?

    We all can be grateful this didn’t happen during the cold war!! It would seem that the Russians do have a good idea:
    There are plenty of asteroids out there!! It’s a pity that third-hand smoke damage and extensions of smoking bans swallow the funds that could be used for this.

    Perhaps we all should be grateful this meteor did not hit Teheran?

    (Add a little hot water, lemon and whiskey [Talisker is a little “peaty”; perhaps a single malt will provide a nice smoothness] to a glass and add this to your nicotine.
    Works a treat!
