Bright Asteroid Visible Tonight

telescopes in Auriga and Perseus
Where are they? Greece?
Mmmmmmm
The distance for a collision is by definition Earth's radius, which is 0.0166 lunar distances. The "twenty lunar distances" rule you're talking about is for long term probabilities of a collision over many many orbits.
You can never please them all - I wanted it to be short. Shoulda read "telescopes, in the constellations of Auriga and Perseus".
I wanted to give you an idea of where to look if you didn't do anything more than read the short blurb on slashdot.

i caught it with 20x120 binocs .. i was observing from quite a light
polluted place in new delhi on 16/12. it was very high in the sky and made the observation neck breaking!
It was really some experience .. first hunting that quickly moving rock at
the limit of binocs reach and then watch it move w.r.t stars .. and to know
that before 2027, next such event (bright NEO) will only happen in 2004. :-)
i have put my observation log and a plot of moving wt24 and stars here. the log shows some of excitement i went through. not anything of scientific value though.
here are downloadable finder charts prepared using Guide 7.0 to make life a little easier.
here is a MUST SEE mpeg video made by compiling the frames from a 2 hour CCD run on WT24 by Nick James
here is great image showing 1 complete rotation of 1998 WT24
...hits the moon.
Please don't reply something very intelligent like "that's more unlikely, 'cos the moon is smaller than earth".
