Deae sirs,good transparency and decent seeing also for this morning's session,which allowed quite a few independent 5min (IR) or 10min (UV) SERs and images (I have some more IR,not included here).
Thin latitude-oriented dark cloud boundaries were mostly seen today (with two darker equatorial patches near CM). In contrast,Equatorial and SPR were brighter in UV. The two darker patches were also visible in RGB.〓
Two versions of image enhancement are today presented,a gif animation confirms atmospheric rotation (and IR/UV comparison; for the IR gif first and last IR images were used; for IR/UV animation the 07:42UT IR image and the UV image),and a map projection from June 17-20 images gives a global overview of the cloud discontinuity (seen yesterday) and the "hook-like" feature (seen on june 18). A few "mini-hooks" emanating from the latitude-oriented equatorial dark boundaries were seen.
