Alan Dyer is a Canadian astronomy author and photographer, who’s photos have been featured on Spaceweather.com, APOD Astronomy Picture of the Day, the Weather Channel, NBCNews.com, CBSNews.com, Time magazine, in National Geographic magazine, and in many other magazines and calendars.

Today, the following picture has been published on Flickr Explore, and he writes in the information:

This is Comet Lemmon (aka C/2025 A6) in a stack of telephoto closeups, processed to add the frames together, to accumulate the many satellite trails that crossed the frames diuring the exposures, rather than average them out as would normally be done now. This is a stack of 45 x 16-second exposures taken over about 22 minutes (other frames in the sequence were not used as they were trailed slightly due to wind). 

Most of the trails are from SpaceX Starlink satellites, if only by virtue of the fact that Starlinks are by far the most numerous satellites in orbit. But the trails also look blue (the generation of Starlinks current as of this date are designed to reflect mostly blue light) and they run in sets of parallel streaks from several launch batches crossing the field. The comet was in Serpens this night, October 26, 2025. The bright star in the tail is Beta Serpentis. The field is 10º by 15º.
