Michael,
Very nice sketch update. Most summers here we get good cooperation from the weatherman, but not this year.
Thank you for posting this very fine sketch.

Hi,
I had excellent seeing conditions and much lower humidity last night for this observation. I used my 6" refractor at 280x and a nebula filter.
I believe the impact area to be on the upper left in the sketch as it appeared to be an elongated, darkish and irregular band in te NPR It just didn't exactly superimpose itself on the somewhat lighter pre-existing band located there.
Tonight also presented the NTeB with a rift instead of a single fuzzy band.
I guess at this point the impact sight will fade significantly.
I used 4H and 2H pencils with the darkest features using a HB.
Best,

stunning observation as always Sol 
you were able to push the magnification to an unusually high 280x i see from your report. i often can't go much higher than 200x, your seeing must have been excellent indeed
how high was Jupiter at the time of your sketch?

Thanks very Kris.
I hardly ever get to go above ~225x for Jupiter, so this was a rare exception. I guess Jupiter was over 1/3 up approaching meridian.
BTW, does any know where there is accurate Jupiter previewing freeware? My old program seems to have gone wacky.
Thanks,

Sol,
Excellent sketch! You captured that concentration in the SEB following the Great Red Spot as well as the disturbance in the South Tropical Zone also following the GRS. I've seen them in images but haven't been able to detect them visually--perhaps they require the excellent seeing that you enjoyed.
I observed Jupiter and the WIS a little after you did (from 1:25-2:15AM local). I agree, the impact is dimming significantly. I didn't make a sketch but posted a report on the Dark Impact thread in the SSO forum.
I use the WIMP program written by Jeff Beish for planets but I don't remember where I downloaded it. Maybe the MarsObservers Cafe or the International Mars Patrol?

Sol,
An outstanding observation of Jupiter showing a wealth of detail, including the Wesley Comet Impact Scar (WCIS). You have recorded interesting detail over the North Equatorial Belt (NEB) and South Equatorial Belt (SEB). The South Temperate Bely (STB) extending into the South Tropical Zone (STrZ) is interesting as well. The Great Red Spot (GRS) appears homogenous with a darkened southern border. The WCIS appears very elongated but noticeable over the South Polar Region (SPR). Thank you for sharing it with us all.
Carlos

Thamks Tommy.
The impact site is certainly an interesting event.
