Comments: Imaged Saturn May 18th targeting a CM transit of the Lat-55 bright spot. These data cover 90 min’s of Saturn rotation and I measure the targeted spot to be at approx Lat-54.9 L3 342.9. The Eastward drift of this spot is very consistent at approx 3.2 L3 degrees /day. I also note a v-bright feature in the EZ at approx Lat+4.9 L1 28.
