There have been numerous disgustingly fake 'nightscape' composites flooding the web where someone had merely pasted a deep astronomical image of comet C/2026 A6 #Lemmon into some landscape, making it look like it was a giant rivalling Ikeya-Seki oder West - oh, how I hated that. And what a relief that NOIRLab has now posted - https://noirlab.edu/public/images/iotw2549a/ - this beautiful and apparently unmanipulated picture of Lemmon over Mauna Kea on 12 November. Yes, it reached 3 point something mag. and had nice tails in the end but it was not a great comet by any means: just look how small and faint it appears next to the southern Milky Way!
The comet #Lemmon show goes on ... images by M. Jäger and G. Rhemann from the evenings of 26 and 27 October: see https://skyweek.wordpress.com/2025/10/27/das-nordliche-finale-der-komet-lemmon-show/ for technical details (and more).
A few hours ago there was a live broadcast of pictures being taken of comet #Lemmon from Japan: https://www.youtube.com/watch?v=Edx5sVaptu0 - the quality of the practically raw images was quite impressive.
Comet #Lemmon ... bathing in #aurora ... seen from the #ISS: another Kimiya Yui photograph - https://x.com/Astro_Kimiya/status/1981845320653734318 - with Gemma in CrB the bright star on the left.
Amazing raw (!) images of comet #Lemmon with different optics and cameras in the live webcast https://www.youtube.com/watch?v=tD0jJnuuwq8 from Italy from 2 1/2 hours ago.

My first capture of comet #Lemmon 45 minutes ago! Under the most crappy conditions - as outlined in https://www.facebook.com/dan.fischer.393/posts/pfbid0TkKrY8H2H1brFytp38psyF5gounAyAEjmnqZyez72jRMDaqHEEHRMqRT3tkJw45xl where also more pictures are shown and technical data given - but at ~4.3 mag. according to https://cobs.si/obs_list?id=2606 and with a highly condensed coma the comet made it through in seconds, even with a bit of tail.
After a complicated and one good sighting of #comet #Lemmon from #Bochum, Germany, on 20 and 24 October - see the thread https://mastodon.social/@PlanetariumBochum/115430462668539532 - more cloudy evenings followed ... but here is the comet again on 30 October, picked blindly out of a suuuuper-crappy sky with 4 seconds at f/2.8 and ISO 1600, right above 9 Herculis. Detection #3 ... and there would be one more today (see the following boost).
A remarkable video clip taken on the #ISS was just posted at #Lemmon rising with a substantial tail - and numerous #satellites flying around.
Tonight comet #Lemmon was picked up by several wide-angle webcams in Europe: https://x.com/JAtanackov/status/1977456751831093352 at the Raxalpe in Austria (left) and https://bsky.app/profile/huubeggen.bsky.social/post/3m2zhian3722b in Abisko, Sweden, together with aurora. Its brightness - https://cobs.si/obs_list?id=2606 - is around 5.2 mag. now and the degree of condensation 5 to 7, so for these cameras the comets looks like a slightly fuzzy green five-mag. star.
