It's currently in Cas approaching the vicinity of NGC 7789 over the next few days. SkyTool's reports it's current magnitude at 8.6. I hope to get a look at it with my 90mm and binoculars some time this week.

Weather cleared last night so I was able to image the comet.
The comet is low in the northeast just clearing tree tops.
A bright nucleus and some coma showing in the image.

I made an attempt with my 90mm last night from a Bortle 3 site but I couldn't spot the comet although transparency was very poor. There was a lot of moisture in the air. I'll try again sometime soon I hope.

I finally spotted it last night after several failed attempts.
I used this finder chart
It was close to the M-52 star cluster which made it easier to find.

I saw it myself as well near M52 with my 200mm. A noticeably brighter nucleus and circular coma. Had my final look at Comet PanSTARRS the same night. Tried for Comet LINEAR in Cyg but couldn't spot it. Two out of three ain't bad.

I got a view of Comet Lemmon through my 10" Dob on July 6th. My notes:

Lemmon's coma was concentrated and round like an unresolved globular cluster, but had an off-center stellar pseudonucleus. A faint cyan tinge was visible in the inner coma. Coma diameter was about 3.5'. A very faint, fuzzy tail was visible to the SSW, no more than 10' in length. Sketch: http://skytour.homes...12F6-130706.jpg

Thank you for this nice sketch ! This is motivating for all of us to observe this comet.

Great sketch. Thanks for posting your observation.
The comet has faded somewhat since July 07. It still is
showing as a green fuzz ball in images as can be seen by
my wide field image taken on July 15.
