If you're going to make fact-like statments of this sort, it would be nice of you to cite the source so we can tell if you're just making it up or not. Thanks.
With some research, it appears to be at least semifactual. Where did the rest of the reasoning come from? You?
At the
Goldstone asteroid schedule, I see this entry:

2008 Jan-Feb 2007 TU24 Yes Yes Requested. Extremely strong target.

I don't see "need astrometry" although some other items have a similar phrase, e.g.:

2009 Jan (136849) 1998 CS1 Not yet Yes Astrometry needed in late 2008 just before closest approach

(Edit: Oh, there's a "Needs Astrometry" column marked "yes". OK. It needs astrometry. Fine.)
Do you think they think it's going to impact Earth? Why do you think they are scheduling 2007 TU24 observations past closest approach and into February?
Anyway, since it will be around again in the future, it sure is wise of them to make measurement of the object during this miss, so they'll have a better idea of where it will be in the future. Or do you think they shouldn't study it because if they do study it, then people might take that as a sign they are confused and in panic?
