It came through dirty skies last night as a fuzzy blob.
No nucleus was visible but interesting just the same...and quite high in the
sky too.

Looking at your FAQ -
"Q. What causes the seasons?
A. The seasonal variation of weather on the Earth is affected by many
things, but the principal factor is the tilt of the Earth's axis with
respect to its orbital plane"
The principle cause of seasonal weather patterns (seasons) is the
length of time a given location spends in direct solar radiation or in
the orbital shadow of the Earth.In short,do not correlate the position
of the Sun against the Equator or any apparent variation in its arc as
the cause of seasons due to a pseudo-dynamic of variable axial tilt .
Just to show you how dumb you really are -
"What it is, actually, is the Earth's rotation. If the Earth didn't
rotate, then all the stars would stay in place, and observing the
night
sky at high power would be easy. Of course, day and night would last
about 4,380 hours each, leading to baking temperatures during the day
and way below freezing at night."
You believe in a 'sidereal time' geometry where the Earth keeps the
same face to the Sun over an annual orbit -
http://en.wikipedia.org/wiki/Image:Tiempo_sid%C3%A9reo.en.png
The problem is that creatures like you will start making false
correlations between terrestrial climate and the Earth's motions or
the Sun's output.
The utter stupidity of not even grasping the basic axial cycle
disqualifies this present generation from even approaching
climatology through the motions of the Earth.
Why don't you take up stamp collecting or something less destructive
because an astronomer you are not.

I wish Sky and Tel would stop saying "under a dark clear sky." 95% of
us live in urban areas now and a mag 7-8 object needs a decent sized
telescope to be seen with any visual impact at all.
Comet LINEAR (C/2006 VZ13), now crossing through Draco and Bo=F6tes, has
far exceeded expectations. It was originally predicted to peak in
brightness around magnitude 10, a pleasant spectacle for people who
enjoy viewing faint comets through telescopes. But the latest
magnitude estimates range from 7.5 to 8.0, making it an easy sight
through 10=D750 binoculars in a dark, transparent sky.

I looked at it through 10x30 IS binoculars from the LAAS dark sky site
this evening, and it was indeed rather easy with dark but not exquisite
skies. I think even 7.5 is pessimistic; I didn't carefully compare it
with any star, but it seemed even brighter than that.

I ran out for the first time tonight to try to catch this little sucker
with 11x80 binocs from the light pollution on the Southeast corner of my
little Iowa town. I expected to pick up a pretty easy glow, but
struggled to see a vague "suspicion" using the triangle of 3 little
stars just above Alkaid on S&T's online chart. I wasn't very satisfied
with this, so I set up my C8 at the bottom of the hill by my house to
avoid some of the lights of town, and a few feet from the growing corn
to my East to give me a bit of a "dewcap" in that direction. After a
little finagling around to find it, I confirmed a rather unimpressive
but certain fuzzball. I'm sure it would look much better with a darker
sky and better dark adaptation. A telescopic satellite buzzed the field
while I was looking a little after midnight. Might see if I can figure
out what it was from Heavens Above... :)
After that, I swung around to view the deep sky Disneyland around
Sagittarius... picked up M8, (the cluster was more impressive than the
nebulosity tonight,) M20, (I've always gotta crank up the mags and
darken the sky a bit to see the "trifid" lines,) M16, 17, 22, 11, and
on. Not really observing, just dropping in on old friends.
I'm not much of a planet watcher, but Jupiter was nice tonight. I
left my higher power eyepieces in the house, and didn't bother dragging
out extension cords for my drive, but he was nice and sharp with 3 moons
to his West and one off to his East, with what I assume was a satisfying
little moonshadow just West of his Northern edge. A nice dark band on
his Northern half with a couple of "knots" on it's bottom edge, and
hints of many more bands if I'd just brought out eyepieces to crank
things up a bit, and darken the glare...
As I dragged in my tripod, I noticed patchy clouds were moving in
fast from the West.
OK, I TOLD you I wasn't a good planet watcher...

Mitch was asking
>You braggin or complainin?
Hmm. :) Don't mean to look like a blowhard or something. I reread my
thing, and I think I'm ramblin'. I don't think my observations are too
impressive for a C8 through the light pollution from the edge of a tiny
Iowa farm town. I DID say that I had trouble seeing LINEAR with 11x80
binoculars, which hardly makes me Walter Scott Houston, and all the the
M's I mentioned are almost gaudy showpieces.
When I post anything resembling an "observation report" in here, I
print it off the next morning and cut it out and glue it in my extremely
informal, totally worthless to anyone else, observing log. Please
tolerate me, like and old man sitting on a bench in front of the
drugstore.

Were you viewing from the city or a dark sky site?
