Hi all, I've just performed a single-night recovery of 2003 SQ168, it's within 1' from predicted position at mag. 20.6-20.8 R. Astrometry just sent to the MPC....
Hi Andrea, With the use of the last observations of 2007WD5 the propability of the impact with Mars grows to about 4.5%! Best regards, Ireneusz Wlodarczyk ... ...

Hi Folks, I am currently working the lightcurve of 5331 Erimomisaki. After a few nights of data, it is pretty clear that it has a period of about 24 hrs and an...
Hi All, My software has turned up another pair of asteroids (Hungarias this time) in essentially the same orbit: (63440) 2001 MD30 Epoch 2007 Oct. 27.0 TT =...
This pair of objects is fascinating on several levels. First of all, I agree, two orbits cannot remain so similar for any significant amount of time, nor can...
Are the orbital arcs long enough that integrations over umpteen thousand years has any meaning? And would it help if there were archive plates available...

AstDys shows the one-sigma variation in "a" for the three-opposition 2004 TV14 at 1.6e-06 AU, which is 35% of the difference between the "a" value for 2004...

The current orbital arcs are sufficient to examine the question of how fast they diverge due to planetary perturbations. for example, the shorter arc, of 2004...
Wo, I'm impressed at how quickly people on this list resond with useful contributions. A longer arc can't hurt, but as I mentioned in my post to Brian Skiff,...
Nice job, Reiner, tracking down an image that nicely shows 2004 TV14. Since you've already got a good head start, please feel free to submit as much (or as...
Out of curiosity I ran a plate-search for (63440) against the catalogue we have to see what other plates might show the asteroid. A considerably trimmed...
