I like the atmosphere of you small sketch.
It was the 8th observation I made of Lovejoy, it's always a gift!
Here join my last sketch, this morning it was the first time that I can detect some (very light) difference in color between the tail and the coma and also the first time that I can see details in the coma, around the nucleus.
- Left the binocular view (10x50) a tail of around 3°
- Right a refractor 102/1000 view with 10, 26 and 40mm EP
Clear sky to you all !

I too got up early this morning to catch this view of Comet Lovejoy. Skies were dark and clear with no moonlight so I was able to see the comet with the unaided eye directly once the comet cleared the trees to my NE. It was an easy find ~1.5° NW of Beta Bootis with binoculars. I was glad it wasn't further south near Spica because the zodiacal light was very bright around there.
I looked at Lovejoy with my 12x36 binoculars and at 15x with the 108mm reflector before I made the sketch. I did a quick and dirty mag estimate with the 12x36's using the defocused star method and nearby 40 Bootis (mag 5.6) as the comp star. Lovejoy was significantly brighter than 40 Bootis.
The coma was well condensed and the tail was visible at low power for over 3° flowing to the NW. It appeared to have a greenish hue at 12x and 15x which went away at 29x. The tail was much brighter closer to the coma and dropped of in an uneven manner with the eastern side persisting a little farther.
This is a pleasing comet to view because of its "classic" appearance with head and tail rather than a fuzzy blob.
Lovejoy appeared to travel ~10 arcmins to the NE during the half hour I was sketching it. While I was observing, 4 different satellites went through the FOV of the binoculars or the reflector including a pair in the binocular FOV that actually crossed paths. Good thing they were at different altitudes.
Conditions were cold--20°F/-7°C--which added a level of difficulty to the exercise since I needed to work fast. As soon as twilight and the thin crescent Moon began to arrive, detail immediately started to wash out but I was done with the sketch by then.
This is my second view and first sketch of Comet Lovejoy--hope I get to see it some more.

Just nice to have two big bites per night.

I didn't have access to the darker skies I would have preferred to have off to my south. So the best I could do was find a spot that didn't have much towards the ENE:
Dec. 12.45 UTC, m1 = 5.3, Dia = 8', DC = 7, Tail = 1.2-deg in PA 345 w/15x70 binoculars.
Location: Deer Creek Resevoir, about 5 miles north of Alliance, OH.
First 30' of the tail has high-surface brightness, and would probably have been visible under suburban skies.

I made my third observation of the comet this morning using my 12x36 image stabilized binoculars. I had planned to use the scope, too, but the lock on the door to my observatory was frozen and with the start of twilight not far off I didn't want to take the time it would require to thaw it out.
Conditions were clear and cold--seeing 4/10 Pickering; transparency 5/6; no moon; temperature 17°F (-8°C). The comet's altitude was 26° at the time of my observation.
Lovejoy was an easy find with the binoculars ~6° south of M13 and ~2° SW of Zeta Herc. The tail extended ~2.5° at a PA of ~345° and I had a hint of more tail trailing out another degree or so.
I compared the comet's brightness to M13 (mag 5.7), Xi Coronae Borealis (mag 4.8), and Upsilon Coronae Borealis (mag 5.8) using the defocused star method. It appeared a little brighter than M13 to me and the coma appeared close to the size of M13. Lovejoy has dimmed since my last observation a couple of weeks ago. I could not detect it with the unaided eye (but I don't have very good eyes).
13 Dec. 2013 1105 UT m1= 5.4 DC= 7 Dia= ~15-20 arcmins
Forgot to mention I saw two Geminids in the area of the Keystone and watched a northbound satellite pass right by Lovejoy--all inside of 10 minutes.
