Saturn July 17th white spot

Hi All,

Imaged Saturn last evening, all of the computer weather models predicted atrocious conditions but it had been a very clear, still day so I had a go anyway.

The seeing was very fast but I was quite pleasantly surprised with this data. There is a largish white spot on the Southern edge of the great storm remnant, it is very close to the CM in my R channel data from 8:58:16 UTC and RGB from 09:00 UTC. It shows up well in both the R & RGB animations.

I measured its position with WinJUPOS and it is at approx CMIII 127.4 Lat +50.1.
I believe there are several of these features as I have seen similar at various times when I have been able to capture data on consecutive nights.

Have attached 1 R & RGB data set along with animations of all R & RGB data from this session.

Buoyed by my results with Saturn I was up this morning to capture Jupiter but in this instance the predictions were spot on, the seeing was abysmal and I ended up deleting all of my data.

Thanks for looking.

Regards
Trevor

They certainly are Derek, that Saturn paper included one of my storm images from the earlier stages of last years great storm, 14 days after it started. The same paper was also published in the US S&T in the May edition.

Thanks Ray, there is a persistent dark spot and I think. multiple white spots along the great storm remnant and given good seeing there is still detail to be seen within the NEB, unfortunately the seeing for this data was not up to resolving more than just the one white spot.
