Have some rather interesting data from March 19th. Captured over approx 2 hrs. Seeing was fair initially but dropped off as time went on.
The conditions were best for my first captures,note that each of my IR images is created from two consecutive data sets that I derotate (5 min's over all) and merge for the final image that I send out.
I see a triangular formation of 3 tiny dark spots in my first image from 16:14:30 UTC. I over sharpened this particular data set and to hi-lite the spots marked them in with arrows on a separate image then presented an unmarked and marked version together.
I have measured the spots in WinJUPOS,both from the original image and also from the Polar Projections.
Lat +68.3 L3 289.5
Lat +67.3 L3 321.4
Lat +73 L3 299.5
I also note that this formation of dark spots are detectable in the polar projection of this data set. I have attached 2 versions of the polar projection as the one file with the spots marked with arrows on one.
What caught my attention with the original data was just how tiny and black the spots were,initially I picked up on the 2 at approx Lat +67 degrees which encouraged me to further sharpening which revealed another spot at approx Lat + 73
I have also looked at each of the two data sets individually that were derotated to make this final image and the spots are detectable in each of the contributing data sets.
I hope for better seeing over the coming week which would greatly assist in resolving this very fine detail.
