Comments: Imaged Saturn May 10th in good seeing, have nicely resolved the Lat-55 bright spot at approx Lat-54.9 L3 5.0. This is my third data point for this spot previously resolving it April 2nd and April 21st. Have started a spread sheet for this feature and now with three data point the L3 Eastward drift over 38 days is 3.25 degrees / Earth day. These data cover 1 hr 50 minutes of Saturn rotation with quite stable seeing for the duration; the 685nm IR data was especially nice. An extensive series of bright spots are resolved mid SEB from limb to limb. This series of spots includes a compact region where the spots are virtually in contact with each other and I have measured the centre of this clump to be at approx Lat-31.9 L3 316.1
