Saturn October 7th in good seeing.

Hi All,

Imaged Saturn October 7th in good seeing targeting a CM transit of the 2010 GWS AV. Have very good 685nm IR and R data while G & B were good. The AV is very well resolved in the 685nm IR data, resolved in the R data and although very faint, even resolved in RGB. I measure it to be at approx Lat+41.5 L3 300.3. The North polar vortex is well seen as are the vertices of the polar hexagon in the polar maps. A bright spot is resolved on the Southern edge of the NNTeB at approx Lat+46.7 L3 243.2, there are several mid latitude bright spots and I have marked one of them at approx Lat+29.8 L3 319.5. A high amplitude ripple impinging up into the NEB is well resolved at approx Lat+15.3 L1 96.5 and a v-bright EZ plume is well resolved at approx Lat+1.9 L1 101.9. The v-thin bright cloud in the NEB is very well resolved in IR and R data, over the last few apparitions this feature has been seen to be associated with the ripples that have been imaged from time to time with the thin bright strip preceding and following the ripple on the edge of the EZ. Agustin, my Professor, tells me they are the result of high altitude EZ hazes that enter the ripple and then get spread into the NEB forming this v-thin bright cloud within the NEB. Note, have considerable data from this session, all has been uploaded to PVOL

Cheers
Trevor

Very scientific Trev. The planetary dissection gives new understanding to Saturn’s bands and clouds that I was never aware of.
Great work well done!

Pretty incredible details. One doesn't realise how many layers and lines there are in Saturn's atmosphere until you actually see them clearly. Awesome work.
