Comet Data updates in Guide?

Jeff Lowrey May 24, 2008

Hi all,

A couple of weeks ago I created a trail (into the future) for C/2007
Boattini W1. That trail showed C/2007 W1 in Hydra early in May and
crossing into Pyxis around May 20. Tonight I did an update on the
comet data in the usual way .... Extras/Add MPC Comets .... etc.
Suddenly Guide shows Boattini W1 in Octans, within 5 deg of SCP! Also
shows a magnitude of 12.1 when recent estimates (within the last 2
days) place it around 5.4!
After some checks it appears to me that the MPC data has suddenly
changed dramatically.

Anyone know what's happening here? ... Or have I goofed again?

Regards
Jeff
