- The only ground-based-observable comets currently known to be
brighter than total visual magnitude 12 are
K5 (near total visual mag 10-11),
(near total visual mag 11-12),
(near total visual mag 8.5-9),
(near total visual mag 8-9).

- Special ICQ
- Joe Marcus has made a prediction for the brightness of comet 169P/NEAT
during December 2009 and January 2010 based on his work with
forward-scattering enhancement due to observing geometry. His
preliminary pre-publication text is available now at

that those sending e-mail to the ICQ or the CBAT remove ALL html-encoded

sending ASCII-only e-mail with contributed observations, so HTML-encoding is
a natural place to attack SPAM e-mail since the vast majority of SPAM has
