No Joy Photographing Comet Lemmon

Well, extremely limited joy at best. Comet Lemmon (C/2025 A6) is in the evening sky right now, 60-90 minutes after sunset, in between the “handle” of the Big Dipper (easy to find in the northwest) and Arcturus (the brightest, orange-tinted star just above the horizon in the west). I could spot the coma (head) with binoculars, just a grey, fuzzy puffball, but no tail. I tried to photograph it both with my iPhone and with the good Canon DSLRs using both the wide-angle “light bucket” lens and the “regular” 50 mm lens. In all of the longer exposure photos there’s a fair amount of light from the porch lights at the neighbors’ houses. I can sorta see a fuzzy dot where the comet should be, but not enough to be 100% sure that it’s it. Tomorrow I’ll take the cameras out to some empty land near our house, away from all of the house lights, and see if that helps.

Meanwhile, the atmposphere today was PERFECT for contrails.

The sunset lighting helped!

I do wonder what causes the sawtooth pattern that’s seen so often. Is that an atmospheric effect, or something caused by some sort of pulsing in the engines?
