Hi All,
Well, just as the Phoenix rose from the ashes, my observatory emerged from the dust. I think our newest IIS contributor, Jonathon, over in New Zealand may have some real-estate from OZ arriving overhead shortly.
All day I had been keeping tabs on the approaching high pressure system and the animated satellite image. We still had wind and cloud cover but the satellite image showed that a vast amount of clear sky was on the way. It looked like the high pressure system may arrive through the night so I cleaned out the dust, three vacuum cleaners full, and wiped down every surface I could reach with a damp cloth that I kept wringing out in a bucket of water.
Had my Peltier cooling system running from 6pm CST and was imaging by 7:30 CST, the seeing was very sweet, semi Bonza and my only problem was trying to keep up with the rate that the temperature was dropping with my Peltier.
I would rate the seeing from 6 to 7 1/2 /10. This really was more of a reflection of my mirror temperature rather then the atmospheric seeing. The relative humidity was down around 30%, the wind had dropped off considerably, the cloud had dissipated and the stars were rock steady with no perceptible twinkle.
My aim on this night was the Wesley Impact Remnant, which crossed the CM at 8pm CST, very early in the night indeed.
I have posted 3 of my 5 RGB's along with the polar projections for those images, with the Wesley Impact remnant indicated.
This feature is extremely diluted now after nearly 3 months. I seem to recall this also being the case with SL9, that the scars took about 3 months to dissipate.
I have also posted an animated polar projection containing the polar projections of all 5 RGB's. I have marked in the position of the Wesley Impact Remnant.

Image 1 has the GRS on the Eastern limb with three conspicuous red spots or barges following in the SEB. There are three prominent white ovals in the STeZ with whats left of the impact remnant above the most western of the three ovals in the South Polar Region.
Image 2 is the polar projection of image 1
Image 3 shows that there are five red spots or barges in the SEB and as is the case in all images, there is considerable activity in the NEB and also some very fine detail in the NTeZ.
Image 4 is the polar projection of image 3.
Image 5 is probably the best image of this session, there are many white ovals in the STeZ, clearly five red spots or barges in the SEB and well defined structure in the NEB, everywhere in this image there is detail to look at. Io is out to the west of the planet.
Image 6 is the polar projection of image 5.
All polar projections were done with Win JUPOS 8.0.13
Thanks for looking.

Trevor
