Your link leads to latest info on tu24.

NASA is confirming the 1.4 lunar distance of closest approach, and giving an orbit that crosses the ecliptic plane one day before closest approach.

Which means? NASA is throwing out the data showing a closer approach or a January 23rd ecliptic plane crossing.

Now, that other data came from observatories, so I guess what I'm wondering now: Will other observatories watch tu24 over the next few days and confirm NASA?

I hope so. I have to say that if it weren't for the maniac in the White House who has a habit of suppressing or fictionalizing scientific data, and also for inventing pretexts for war, I would have a lot more confidence in NASA's info on tu24.

The kind of explosion that would occur from an asteroid impact as big as tu24 could easily be declared to be a nuclear attack, and thus a pretext for war. Nuclear war. Unbeknownst to many people, Bush and Cheney have been trying to fictionalize a pretext to drop nuclear bombs on Iran for about three years.

So, I hope NASA is correct, and I hope other observatories will continue to observe til tu24 is moving away from us.
