Comments: Imaged Saturn April 21st, have only 685nm IR data covering 50 minutes of Saturn rotation. The data was fair at best with the middle of the session, centered on 19:50 UTC the best of it. I note a feature within the NPR which very closely resembles the coupled anti cyclone / cyclone combination which I tracked during the 2020 apparition. I measure the dark spot to be at approx Lat+62.3 L3 74.7 with the bright spot at approx Lat+62.1 L3 87.4
