Jason,
Thank you for the compliment on Jupiter observation and sectional sketch of the Wesley Comet Impact Scar (WCIS). I was impressed as to the darkness of the impact scar. I hope that you get to see it yourself soon.

Jeremy,
Thank you for your compliment on my Jupiter observation showing the Wesley Comet Impact Scar (WCIS). I was fortunate to have good seeing for my observation. I hope to follow the impact scar soon.
I agree with Pete that your sketches are terrific!

terrific observation of the impact scar carlos  you also noted very much details within the bands, i wish i could see that much detail 
the close up sketch of the scar is awesome!
i see you use a lots of colors in the sketch, do you actually see the planet in those lively colors at the ep  the best i can do is see a slightly yellowish teint sometimes. saturn however is notably more yellow imo.

Terrific sketches Jeremy, Tommy and Carlos!  I was delighted to have a chance at a sketch of the WCIS very early in the morning today. The image of the pastel sketch caught some glare when I was shooting indoors today, so it includes a few artifacts that are not there in the actual sketch, but we all know how much cameras lie don't we?  Anyway here's my latest attempt at a sketch. (See the next post by Carlos and editorial note below. Thanks Carlos!)
Michael, I'm still learning how to process my Jupiter images, so it may be a while, but I'll definitely post them and let you know where when I do.
Editorial comment: Carlos I love what you were able to do with my sketch in Photoshop! Thanks so much!  I'm so impressed by the improvement that I'm going to replace my sketch image with your version. If your ever have the time, a quick tutorial on your processing techniques for modifying pastel sketches would be very much appreciated. Thanks again!

Rich,
Thank you for the compliment on my Jupiter observation and WCIS sectional sketch. I was impressed with this unique feature over the atmosphere of Jupiter. I am glad that you were able to observe it as well. I took the liberty to process it a little. I hope that you like it.

Beautiful drawing, Rich. I'm always impressed by what you are able to do with pastels, and I'm glad you had a chance to apply them to this event.

T5, Jeremy, Rich, Carlos,
Wonderful sketches from all of you and an impressive visual record of the Wesley Impact scar as it evolves over time.
Carlos, your detailed observation shows what a practiced eye can do with good seeing conditions and good optics. Your computer skills aren't bad either! I really like the sectional sketch of the scar.
I'm still waiting for a clear night to get my own look at Jupiter and hopefully contribute here. Meanwhile, thanks everyone for posting your observations and keeping us up to date.

Thanks Carlos, Jeremy, Michael and Tommy!
Carlos, a very special thanks to you my friend. Your superb digital processing cleaned up the image defects and limb definition and the background black is perfect!  . Your last sketches are stunning, Jupiter, WCIS and moons with such keen observational skill, it takes my breath away!  Seeing your localized WCIS view was astonishing enough, but when I saw the Hubble images, Carlos, I was agape at the agreement!  Superb work!
Jeremy, your last sketch and report are just awesome, your pencil work is sublime! I'm so happy the WCIS is staying around for a while (knock on wood), I want to see as many sketches of this improbable and exciting event as possible.
Tommy, the pastels are very easy to use just make sure you have a small white light or tags to discriminate colors, red light can be murder when dealing with color.
Michael, thanks, wishing you your first of many observing/sketching opportunities of this unique event. It's so wonderful to see all the fine sketches that are accumulating here, hoping yours is next!

Kris and Michael,
Thank you for the compliments on my Jupiter observation and Wesley Comet Impact Scar (WCIS) sectional sketch. I was fortunate to have experienced good weather for the observation. Jupiter presents a wealth of colors especially while using medium to large apertures (>6 inches, but even more notable at >10 inches). My 9-inch F/13.5 Maksutov-Cassegrain provides enough aperture for strong colors but my old 12.5" F/6.2 Newtonian reflector was even better. The cascade of pastel colors over the belts and zones is one of the things that brings observers back to the king of the planets.
Rich- You are very welcome as I only tweaked an already excellent observation. I too was happy with the apparent agreemnent between my impact scar observation and the Hubble Space Telescope (HST) image. I look forward to your future observations.
The best of luck in your observations of Jupiter and the impact scar.
Carlos

I was out this morning and got my first look at the impact that Bird discovered 9 days ago. 
I was all set up early and watched a very nice transit of the Great Red Spot (GRS) across the Jovian central meridian CM) around 0615 UT (2:15 AM EDT). Jupiter was near culmination and the seeing was above average. The GRS appeared a pale tan color most of the time but sometimes a light pink with the seeing.
By the time the impact area had rotated around the limb into view, Jupiter had started to drop back down into the top of the soup and the seeing dropped with it--if I tried to go above 200x, the image became too soft and the impact would disappear.
Even still, at 200x when the seeing would steady I got very good views of this amazing sight. It was very easy to see this unusual phenomenon in the Jovian south polar region. I had wondered whether the impact would have begun to dissipate in the cloudtops, making it hard to spot--no worries, even with average seeing conditions.
I made the sketch as soon as the impact scar had rotated around the limb because I knew that Jupiter was getting lower every minute. I continued to watch as it approached the CM. The impact appeared much shorter when I sketched it near the limb than it did when it was on the CM, probably because of foreshortening.
I made the sketch with HB and 2B pencils on photocopy paper using Sol's template. Blending was done with a stump and my finger. I flipped the sketch digitally to give the "classic" view before adding the text.
I am very happy to have the opportunity to contribute this sketch and observation to the record of this event.

Michael,
An excellent observation Jupiter and of the Wesley Comet Impact Scar (WCIS) over the South Polar Region (SPR). It appears that the impact scar is still very dark and readily visible. I hope that we can all see this unique object soon. Thank you for sharing it with us all.

Tommy, Carlos, thanks for your comments. I found this sketch hard to make because of the distraction of wanting to observe the new feature while meanwhile the GRS was disappearing around the bend and the rest of Jupiter was presenting a lot of detail. It could have been better, but I learn every time I go out.

Excellent sketch, Michael. Great catch picking up the impact scar and GRS while they were both visible.

Rich and Michael and Carlos,
I see more wonderful sketches have appeared here from you guys. I am on the road without a scope and am experiencing crystal clear skies. This is almost painful. At least I have taken pleasure in seeing all your super excellent sketches here. Kris really started a great thread here.
