Details:
Comet C/2025 F2 (SWAN) continues to fade slowly, on the morning of 2025 April 18 UT the comet was magnitude G=9.8 as calculated from 5x20 second images thru a green filter in an aperture diameter of 3'. The comet coma was 2.5' wide and the comet had a fan tail 2' long at a position angle of 309 degrees from the comet coma. There is a lot of speculation about the comet disintegrating, so put together some 4.3'x4.6' FOV images of the comet to maybe help with that conversation, although using a small scope at low altitude with a 75% illuminated Moon is not ideal to see much fragmentation. Included the images from the morning of April 15 when the comet had a nice tail and the morning of April 16 when the tail was gone as seen with a 50mm f/5 Refractor.
