Re: [meteorite-list] Comet May Have Missed Earth By A Few HundredKilometres in 1883?

[Sterling K. Webb]

The "Bonilla Observation" is widely touted in
UFO circles as an 1800's "sighting" of alien
spacecraft. Not mentioned in the Technology
Review article is the fact that Bonilla took
photographs of the objects crossing the Sun:
http://signal.forumotion.com/t108-bonilla-ufo-photos-zacatecas-mexico-observatory-august-12-1883

The above citation also includes a translation
of Bonilla's original report as well as some photos.
A book on photographic identification cited in
http://en.wikipedia.org/wiki/Jos%C3%A9_Bonilla_Observation
says that the "objects" correspond to how such
a primitive photographic aparatus would render
high-flying geese.

There's a link to the Spanish original of
Bonilla's report here:
http://www.perceptions.couk.com/bonilla.html

The editors of "L'Astronomie" comment that:

a) the observation "is not easy to explain" and
b) they "believe that objects in question are
birds, insects, or high atmospheric dust, anyway,
corpuscules belonging to our atmosphere" so
there was doubt in 1883.

There's doubt in 2011, too. Phil Plait (the Bad
Astronomy blog) raises a number of excellent
objections:
http://blogs.discovermagazine.com/badastronomy/2011/10/17/did-a-fragmenting-comet-nearly-hit-the-earth-in-1883-color-me-very-skeptical/

Gizmodo (and dozens of copy-cat bloggers) calls
it "the day all life on Earth almost ended."
http://gizmodo.com/5850500/the-day-all-life-on-earth-almost-ended
And so on, throughout the scientoblogosphere...

Did anyone notice the date of the observations
coincides with the annual Perseid meteor shower?
I submit that they also fit the description offered
by Bonilla. Perseids observed through the telescope
are strikingly similar.

Nineteenth century astronomy is replete with
accounts of mysterious objects transiting every
observed body, mysterious shadows, abrupt
short eclipses, and other phenomenon that
could be (and have been) interpreted as close
approches of small bodies. Just page through
Charles Fort's books for a sampling.

Billion Tonne Comet May Have Missed Earth By A Few Hundred

A re-analysis of historical observations suggest Earth narrowly avoided
an extinction event just over a hundred years ago

On 12th and 13th August 1883, an astronomer at a small observatory in
Zacatecas in Mexico made an extraordinary observation. José Bonilla
counted some 450 objects, each surrounded by a kind of mist, passing
across the face of the Sun.

Bonilla published his account of this event in a French journal called
L'Astronomie in 1886. Unable to account for the phenomenon, the editor
of the journal suggested, rather incredulously, that it must have been
caused by birds, insects or dust passing front of the Bonilla's
telescope. (Since then, others have adopted Bonilla's observations as
the first evidence of UFOs.)

Today, Hector Manterola at the National Autonomous University of Mexico
in Mexico City, and a couple of pals, give a different interpretation.
They think that Bonilla must have been seeing fragments of a comet that
had recently broken up. This explains the 'misty' appearance of the
pieces and why they were so close together.

But there's much more that Manterola and co have deduced. They point out
that nobody else on the planet seems to have seen this comet passing in
front of the Sun, even though the nearest observatories in those days
were just a few hundred kilometres away.

That can be explained using parallax. If the fragments were close to
Earth, parallax would have ensured that they would not have been in line
with the Sun even for observers nearby. And since Mexico is at the same
latitude as the Sahara, northern India and south-east Asia, it's not
hard to imagine that nobody else was looking.

Manterola and pals have used this to place limits on how close the
fragments must have been: between 600 km and 8000 km of Earth. That's
just a hair's breadth.

What's more, Manterola and co estimate that these objects must have
ranged in size from 50 to 800 metres across and that the parent comet
must originally have tipped the scales at a billion tonnes or more,
that's huge, approaching the size of Halley's comet.

That's an eye opening re-examination of the data. Astronomers have seen
a number of other comets fragment. The image above shows the
Schwassmann-Wachmann 3 comet which broke apart as it re-entered the
inner Solar System in 2006. There's no reason why such fragments
couldn't pass close by Earth.

One puzzle is why nobody else saw this comet. It must have been
particularly dull to have escaped observation before and after its close
approach. However, Manterola and c

[MexicoDoug]

We listees know the Mexican astronomer in this article, for another 
reason -  he is the one who managed to write up the account of the 
Mazapil iron meteorite, which he also attributed to have come from 
fragmenting Comet Biela in that same time frame.  I'm from Missouri on 
this one, as much as I would like to believe that Mexican skies are the 
nicest in the world (which of course is not true anymore, but some are 
still quite good).


I would put more creedence in this if I already wasn't pissed off at 
the incredible description of dancing meteors he described durning the 
fall of Mazapil, but, for all the detail, of sizzling iron, there was 
absolutely no mention of which direction the fireball was observed.  
Even at that time, a key piece of information that would have quenched 
later debates about meteorites being larger cometary masses which was 
widely believed or tolerated at that time.


Kindest wishes
Doug

Dear List Members,

A couple days ago I posted a preview link to a new meteorite I would like to
announce - Northwest Africa 6566, a new Polymict Eucrite with a low Total
Known Weight of just 145 grams in a single stone.

This exciting meteorite has a very busy matrix with rare diogenite clasts,
basaltic xenoliths and a shock rating of 2-4. I purchased this from a dealer
at the 2011 Tucson Show. A very small end piece was initially sent to Ted
Bunch in 2010 to determine if this stone was a meteorite or not. He
determined that it was a meteorite, but a full type sample would be required
to provide a proper classification. Upon first examination, I thought it
looked very similar to some of the Omani lunar meteorites, but this stone
was discovered in Northwest Africa! Without wanting to let this interesting
meteorite get away, I agreed to the high asking price and submitted the full
type sample after returning home in February.

Here is part of Dr. Bunch' submitted classification to the Meteoritical
Society, the Official entry in the Meteoritical Bulletin is edited and
shortened:

Northwest Africa 6566
Petrography (T. Bunch and J. Wittke, NAU): Shock-melt generated,
fine-grained granular to subophitic basalt matrix with basaltic xenoliths
and rare diogenite and glassy shock melt clasts arranged in flow
orientation.  Post crystallization shock, S2-4; weathering grade is low.
Component modes (vol %): matrix, 69: xenoliths, 18; shock melt, 8;
diogenite, 5.
Mineral compositions: Matrix: orthopyroxene Fs64.5Wo4.1, Al2O3 = 3.2 wt %
(FeO/MnO = 28); augite, Fs29.8Wo42.6, Al2O3 = 4.5 wt %; plagioclase, An89.
Diogenite clasts: orthopyroxene, Fs31.1Wo1.5 (FeO/MnO = 27); olivine Fa43.1
(FeO/MnO = 64); chromite cr# = 79.
Classification: Achondrite (polymict eucrite). Unusual eucrite in that a
shock melt liquid was generated either within the parent body regolith or at
shallow depth, enveloped clastic debris during a flow stage, cooled rapidly,
followed by post crystallization partial recrystallization.

I would like to now provide the list of all available specimens which is
only 24 pieces. If you are interested in the price list, please email me
privately. Enjoy the images!

Hello there, fellow space rock aficionados.
I need to thin out some of my excess collection pieces.
I've either got duplicates, acquired a larger specimen, or whatever.
Most of you have more advanced collections than mine anyway,
but there's some good stuff here, so you never know. Take a peek.
Almost all have well-known provenance. I'm working on a price list.
If there's anything you're interested in, let me know.
I have photos for most, but not all (yet).
Thank you for looking.

Dear List Members,

A couple days ago I posted a preview link to a new meteorite I would like to
announce - Northwest Africa 6566, a new Polymict Eucrite with a low Total
Known Weight of just 145 grams in a single stone.

This exciting meteorite has a very busy matrix with rare diogenite clasts,
basaltic xenoliths and a shock rating of 2-4. I purchased this from a dealer
at the 2011 Tucson Show. A very small end piece was initially sent to Ted
Bunch in 2010 to determine if this stone was a meteorite or not. He
determined that it was a meteorite, but a full type sample would be required
to provide a proper classification. Upon first examination, I thought it
looked very similar to some of the Omani lunar meteorites, but this stone
was discovered in Northwest Africa! Without wanting to let this interesting
meteorite get away, I agreed to the high asking price and submitted the full
type sample after returning home in February.

Here is part of Dr. Bunch' submitted classification to the Meteoritical
Society, the Official entry in the Meteoritical Bulletin is edited and
shortened:

Northwest Africa 6566
Petrography (T. Bunch and J. Wittke, NAU): Shock-melt generated,
fine-grained granular to subophitic basalt matrix with basaltic xenoliths
and rare diogenite and glassy shock melt clasts arranged in flow
orientation.  Post crystallization shock, S2-4; weathering grade is low.
Component modes (vol %): matrix, 69: xenoliths, 18; shock melt, 8;
diogenite, 5.
Mineral compositions: Matrix: orthopyroxene Fs64.5Wo4.1, Al2O3 = 3.2 wt %
(FeO/MnO = 28); augite, Fs29.8Wo42.6, Al2O3 = 4.5 wt %; plagioclase, An89.
Diogenite clasts: orthopyroxene, Fs31.1Wo1.5 (FeO/MnO = 27); olivine Fa43.1
(FeO/MnO = 64); chromite cr# = 79.
Classification: Achondrite (polymict eucrite). Unusual eucrite in that a
shock melt liquid was generated either within the parent body regolith or at
shallow depth, enveloped clastic debris during a flow stage, cooled rapidly,
followed by post crystallization partial recrystallization.

I would like to now provide the list of all available specimens which is
only 24 pieces. If you are interested in the price list, please email me
privately. Enjoy the images!

Hi Dirk,

Maybe on the Moon ;-)

Wait ... what a boring place the Moon must be.  There are no meteors or 
bolides there, just surprise impacts seemingly from nowhere.


2009 TM8, the one that approached closely at a hair under a Lunar 
distance, has already whizzed by an hour before your post.


Kindest wishes
Doug
