Dear sirs,good transparency and decent seeing 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).
The cloud discontinuity is very well seen in IR images,and is located under a region which is clear (darker) for UV. in also seems smeared when compared to IR images,though image quality is poorer in UV.
A dark NPR collar is also seen in IR,and a bright UV region is just S of it.
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 07:30UT IR image and the 07:47UT UV image),and a map projection from June 17-19 images gives a global overview of the cloud discontinuity (seen today) and the "hook-like" feature (seen yesterday).
