"This incident, along with previous NEOCP postings of the WMAP spacecraft,

...A.U. Tomatic
Hi Listees,
I just extracted this from the web page Chris kindly provided with the
"awakening" :-) Good material for a sci-horror thriller....
Looks like 1 AU Tomatic is the fall guy signing off. I don't think the
ESA will bother to register Rosetta on their Space Junk webpage.... If
there wasn't a sense of humor before, there certainly is one now.
Statistically, one needs to strongly question whether someone knew what
what happening and just wanted to see if they could pull it off. Seeing a
spacecraft traveling 12 km/s still six and a half days away on a near
collision course with Earth and not raising a scandal of what if's knowing
it's size conveniently ... even if you knew exactly where to look this is
all pretty incredible. It almost deserves a designation for that alone
... found it right where it was supposed to be at around the 20th
magnitude or so? Can anyone locate the honorable Dr. AU Tomatic ? I 'm
not getting my hopes up about how well "we" can detect these objects....it
still smells like a prank to me.
Keep Looking Up,
Doug

So, will closest approach be 20:57, 21:04, 21:13 UT, or undetermined, and
who will get the view? I think Rosetta won't be rising until 21:15 where
I'm at in southern North America, and at close approach will be moving at
around 3 degrees (6 full moons) per minute. That is a little
challenging.....especially if the spacecraft is not oriented to reflect
much back.
Thanks kindly,
Doug

Yep. It's the Rosetta spacecraft making its planned gravity assist
fly-by of the Earth.

Hi List:
I am trying this again since my previouys forward did not appear to go
through.
On November 13, this newly-discovered asteroid (only about 20 meters
diameter) will pass within 2 Earth radii of the CENTER of the Earth
(that
is close). It will be 9th magnitude (about 50-100 times too faint to
see
with the naked eye), but show be observable with a small telescope (if
it
is night where you are when it comes by and you know were to look).
Go to the cfa.harvard site for coordiantes, etc. I can interpret
columns
if you are interested.
I am sure there will be more about this in the coming days.

Subject: Re: {MPML} 2007 VN84 incoming
2007 VN84 is significant in that it not only comes closer, it is much
bigger, around 20 m in diameter, compared to 2004 FU162 only about
1/3 that
size. Based on our recent population estimates, we expect an object
the
size of 2004 FU162 to pass within a couple Earth radii about once a
year,
and to actually impact (actually, blow up in the upper atmosphere)
about
once in five years, so the only thing unusual about 2004 FU162 is
that we
saw it as it passed by. 2007 VN84, on the other hand, is so large
that we
expect omething that big to come as close as 2 radii only about
once in 20
years, so it is a remarkable event in itself, in addition to the
fact that
it was discovered and can be watched flying by. Congratulations to
Richard
Kowalski and the Catalina Sky Survey.
Cheers,
Alan
P.S. I second his request and interest for a lightcurve, but it
will be a
real challeng on account of its rate of motion. Plenty bright
enough, but
really truckin'.
