Imaged Saturn July 27th in reasonable seeing targeting the +63 disturbance. When putting together my animation of 685nm IR data covering 80 minutes of Saturn rotation,along with the +63 spot I notice an elongated dark feature in the EZ.. I measure the EZ feature to be Lat +0.7 L1 3.5 L2 184.3 L3 100.6.
Looking at each 685nm IR data set in isolation this dark feature is easy to miss but is easily seen in the animation so I think it is real and not an artifact.
I note that the +63 dark spot continues to drift at spot on -11.4 L3 deg/day.

Here are the images from 27th July taken in relatively poor seeing...also,
well after culmination/transit which we have found to be not terribly
conducive for good image outcomes this apparition. (for some unknown

The rgb (colour) image was taken with the ASI224MC colour camera & any of
the details that are evident on the disk are testament to this camera's
sensitivity,despite unsatisfactory seeing...

The iR742nm image - & in particular the NPP of this image (these taken with
the mono ASI174MM camera) did show the +63N rift/feature & the associated
elongated dark spot very well however.....a quick (& rough) measurement in
WinJupos reveals this dark Northern spot to subtend over 20 in L3..! This
is very large in our opinions.
