Obervations from Goldstone Radar
Goldstone radar observations of near-Earth asteroid 2007 TU24 last
night were successful.
The observations reveal an object roughly 250 meters in diameter, with
an interesting shape, and strongly suggest that rotates slowly.
The radar astrometry we obtained reduced the asteroid's three-sigma
range uncertainty at 00:00:00 UTC on Jan. 24 from about 2/3 of an
Earth radius to ~30 meters. Consequently, we have cancelled our
request for optical astrometry to support the rest of the radar
campaign.

If WD5 is passing Mars at a short distance of only 16,000 miles, and we supposedly have equipment already set up to catch footage, this will be so interesting ! Then my friends we will get to see what a real NEO will do. I for one cant wait! I just hope that little guy walking around and the window washers are safe

"... with an interesting shape"
what does this mean?
the "very interesting shape" of the asteroid suggested that it was a "contact binary", or two asteroids that fell into each other after a period of orbiting each other.
The radar observations also suggest the asteroid is rotating slowly – perhaps once every 10 to 30 hours, he estimates based on the initial observations. Studying rotation rates can provide clues about whether an asteroid is a solid rock or a loose collection of rubble,

Antar's quote,
Now what is your take on this situation?
I'm not having any horrible dreams yet, like I did before 9/11. I don't think TU24 will cause a problem on the 29th.
My birdies will be back & Thanks for the help.
