Comet McNaught 2007 observations

Fri Jan 19 1835 MST (Jan 20 0135 UTC)

Observing from the Nederland area I saw two of the striae in the outermost
portions of the tail naked eye. They extended about 10-15 degrees above
the horizon. Four or so were visible in 10x50 binoculars.

Mon Jan 15 1215 MST (1915 UTC)

Saw comet just after noon in 10x50 binocs, perhaps magnitude -4 or -5 still.
Somewhat challenging with a slight haze brightening up the aureole around the
sun. Comet was to the lower left of the sun. Short length of broad tail was
visible. Observing from Boulder.

Sat Jan 13 1640 MST (2340 UTC)

Saw comet in 10x50 binocs after the sun set behind a cloud bank and the
mountains. The sun was still above the horizon however with sunset about
1700. The comet went in and out of the clouds for about 15 minutes and I had 
a naked eye sighting about 1641. Tail was short and broad compared with before
and it pointed to the upper left (about the 11 o'clock position). Observing 
from Gunbarrel. Magnitude was -4 or possibly -5.

or so depending on clouds and such.

to upper right, setting after the comet behind the mountains 3 degrees high.
