Hi

Got a short bout of fairly good seeing between showers and was able to image the region of the equatorial spot shown in a previous post. It's still in roughly the same location as it was over a week ago (~L1=250) and looks similar (maybe a bit bigger), assuming that the L1 system applies to the region around the spot. System 1 longitudes were measured in WINJUPOS. The spot and associated structure can be seen in the LRGB, but the heavily enhanced luminance image shows it somewhat better. The third image is the original sighting from the 7th of June, with the spot almost on the CM.
thanks for looking. Regards ray

Excellent work Ray, I think there are 2 spots with the one closer to the preceding limb being brighter, certainly something to keep an eye on.

Well done
Regards
Trevor

Nice work Ray. I have yet to pick up any sign of these EQ spots; seeing related I guess..

Good stuff mate.

thanks Rob



Thanks Trevor - you are right, there could be more than one spot - might even be some turbulence structure. would be great to have a bit more resolution...



thank you Vivek



thanks Asi - it was just dead set luck that the same area was presented during the two short periods of reasonable seeing over the last fortnight

regards Ray

Hi Ray, this morning Damian Peach sent me an image of Saturn that included a bright spot in the EZ. Thought you might be interested so have attached a link to his image. When replying to his email I told him about your images of such a feature and sent him a link to this thread.

Wow - thank you very much Trevor - very kind of you. The spot in Damian's beautiful image appears to be in roughly the same longitude as the earlier sightings so it could plausibly be the same feature. If it is the same feature it is quite long lived now - approaching a fortnight. I currently have the scope set up waiting for the clouds to clear so that I can try for another image of it - not looking good though. edit: it rained, but took the time to reprocess the image from the 16th - somewhat better visibility of the spot in this version.

It is quite exciting that someone else might have seen this spot - I was beginning to wonder if my imagination might have got the better of me....



thanks Troy

regards Ray

Nice work Ray. Crisp and containing the spot. Interesting to see Damians image, incredible given his latitude.

These images are just amazing, really curious about Damien's image. Down the RHS off the sphere there is a clear reflection of the rings. Is it caused by a reflective temperature gradient (mirage) or is the reflection given off from the surface :question: Could look at it for hours.

thanks Steve. don't know about the effect you mention on Damian's image, but it certainly is beautiful. regards Ray
