I just returned from three nights in the big city (Santa Fe), during which there was no comet viewing. The sky tonight (25 Oct) was mostly clear at dusk. The crescent moon was partially obscured by thin clouds as it sank behind the Bristol Head ridgeline.
Comet C/2025 A6 (Lemmon) is now brighter than magnitude 4. I was able to see it without optical aid as it hung low over Bristol Head at the end of Astronomical Twilight. With a camera, the view is magnificent. The blue ion tail currently spans more than 7°, and it is twisted and broken by the solar wind.

Comet C/2025 R2 (SWAN) is still there, but fading, in the southern sky. At magnitude 6.6, it is not visible without binoculars or a telescope.
