The faint green glow of Comet C/2023 A3 (Lemmon) crossing the night sky above the rooftops.
This icy traveler from the outer Solar System releases cyanogen and diatomic carbon gases, giving it that distinctive emerald hue.
A fleeting visitor — it won’t return for thousands of years, yet for one brief night, it shared its light with us. 🌌☄️

And here ends the #Comet #C2023A3 #TsuchinshanAtlas thread, with a convincing non-detection. Barring extraordinary circumstances, I shall not be photographing any future apparition

(Canon G7 X, 163x5s, f/2.8 ISO 1250 100mm EFL, Stellarium for reference)

(edit: whoops, had Stellarium on the wrong day. But it's still not there at the correct location either)

#Comet #C2023A3 #TsuchinshanAtlas tonight. Still visible in a single frame but too faint to identify on the camera screen. Globular cluster NGC 6760 is the other (redder, tailless) fuzzy blob identifiable in this image
