There is one more chance to catch a glimpse of this comet for those of us
in the northern hemisphere. It may be visible in *daylight* for a few more days.
These are the approximate offsets in Declination and SHA from the comet to the
Sun for the nest few days at 0 hours GMT:
day dDec
dSHA
13
4.7 -4.5
14
1.2 -5.3
15
-2.6 -5.9
16
-6.3 -6.4
17
-9.7 -6.6
For noon CST (e.g. for Chicago), you want to interpolate 75% of the way
from one date to the next. So for tomorrow Jan. 13 at noon CST, the comet is
about 2.1 degrees north of the Sun and about 5.0 degrees to the left. That's
pretty close but the distance opens during the next few days. Since the comet is
very bright, if the sky is clear it will be visible as a bright fuzzy star in
binoculars. The trick is that you have to look very close to the Sun. Do this
carefully! Stand next to a tall building to obscure the Sun.
And if you prefer the armchair approach, you can watch the
comet live at the SOHO web site:
(for those of you unaware, many minor comets have been discovered by
armchair amateurs studying these SOHO images --but, no, you don't get your name
on it by this discovery method)
