Hi Bill and Group,

I've been trying to work out how close 2003 WX153 got to a occultation
of star GSC 1799 967
I know I have got close.. but here is the strange thing, when I zoom in
on the asteroid and the star, when I get to Level 16 (15 seconds) the
asteroid disapears.
It does however, show at level 15 (30 seconds)
Any suggestions?

BTW the time and date I'm looking at is 18:28:35 28th Dec 2003

Thanks in advance

Alan
