030214.70 -  B  1.0: TT  5.0   B   -    7    <1  9   15     0.3  T Karhula
Comments: Magnitude difficult to estimate due to lack of comparison stars in
the bright twilight. The fainter alfa Aqr was the only visible star in field.
NEAT reminded of a "fuzzy" Mercury.  Altitude 3.8 deg.  20x100 binocular 
showed a small, yellow disc-like coma and short tail.  I could follow the 
comet for 21 minutes, until 17.00 UT when its altitude was 1.1 deg 
and disappeared behind the distant tree-tops. Observed from latitude 
60 deg N.  Comet's elongation 12 deg. Very clear weather. Site: Virsbo, 
Sweden.

Comments:  The comet was faintly visible to the naked eye. The tail curved 
slightly to the E and the W border was sharper. Coma almost stellar and 
intense. NEAT was a neat ;-) sight in a 20x100 binocular.  Altitude 7 
degrees. First quarter moon in the sky.  Site: Virsbo, Sweden.

Note: A very diffuse appearance but not difficult.  Observed the night
before the eclipse together with Charles Morris, Michael Mattiazzo, Andrew 
Pearce, and Reinder Bouma. All of us got similar magnitude estimates 
(11.7-12.0). Site: Roxby Downs, South Australia.
