2004/08/25.151390 This observation was made on 25 Aug at 03:38 UTC.
It was reported by site #932 which is the John J. McCarthy Observatory at Lat. = 41.53N and Lon. = 73.43W

They observed Toutatis at:
RA : 22:04:10.140 (h,m,s)
Dec : -12 46 31.10" (deg,min,sec)

The NASA Ephemeris Generator used as above produces these results for the given Lat., Long. and time:
RA : 22:04:12.13 (h,m,s)
Dec : -12 47 81.1" (d.m.s)

If they are dosent that move the asteroid closer than predicted

Hmm.... the NASA EG for that time, place and target gives me:
22 03 34.20 -12 56 45.6

Anyways, that's not the point. The point is that there is level of uncertainly in Toutatis' orbit, and that uncertainty is represented by the error in its closest approach numbers. I can see that you're worried about an impact. There is no chance of that, even the most severe error puts it far from earth.

As we get closer, more observations will lead to less error and a better model of Toutatis' orbit, which will come in handy for predicting future close passes.
