I am hoping someone would do the calculations for Singapore....I am pretty poor in mathematics....Anyone has seen Toutatis. Last night and hopefully tonight is going to be clear.

Hi :

Moon is sitting less than 8 degree from where the toutatis sits tonite ( 9/24 ) in Microscopium. It will be challenging to pick a 9.87 mag object .

Use Horizons ( nasa link posted by Rich) to generate the ephemeris then. You still need to manually add each coordinate ( RA/DEC)s to the planeterium sw. For the Goto scope owner it will be simpler - just punch in the ra/dec .. and look.

Dear all
