First Saturn for this year,at 25° elevation (maximum for this apparition from Toulouse).
Only the hexagon and his central vortex is slightly visible in this beginning of boreal summer over there,along with a few satellites,as usual:
Seeing was better yesterday morning,processing is in progress.

Had good seeing May 22nd. Clearly the polar storm has survived now over a year. It has certainly changed the structure of the polar region. Still it seems to be quite linear as a chain of spots at approx Lat+65 with a more diffuse feature very close to the edge of the polar hexagon.
I measure two of the brightest spots within the chain of spots to be at approx Lat+65.5 L3 181.5 and Lat+65.7 L3 118.2,the more diffuse feature near the hex is at approx Lat+76.6 L3 142.6.
I also see another isolated bright spot at approx Lat+30.2 L3 141.5 best seen in the R channel data,initially I thought this may be an artefact but on closer inspection it can be measured in both R channel images which are 36 minutes apart.
