Been a long while since I have sent anything out.... On the 3rd Dec we had some great seeing in St. Albans, UK after cloud finally cleared, and this was the best seeing I have had for imaging Uranus since 2015 with skies being both steady and transparent. Moons imaged separately at 100msec exposures with planet at 500x gain and 8.5msec exposure. In this great seeing two possible spots were detected at the border of the polar region. As I imaged over a 2.5hr period I was able to track this longitude over an extended period and an image showing the Uranus at the three different times is also attached. Spots are best seen in last image with the 685nm filter. These are at the threshold of detection and hopefully can be confirmed by other imagers or by HST which I understand may be imaging Uranus soon. Merry Christmas to all of you and your families,
