First the nucleus of #comet SWAN split - https://skyweek.wordpress.com/2025/11/02/allgemeines-live-blog-ab-dem-2-november-2025/#Nov06 ("Der Kern des Kometen C/2025 R2 (SWAN) ist zerbrochen ...") - and now C/2025 K1 (ATLAS) has suffered the same fate: a 2-meter-telescope image from https://www.astronomerstelegram.org/?read=17487 ("Multiple Fragmentation Observed"), also https://groups.io/g/comets-ml/topic/116216567 (several amateur observations) and https://www.astronomerstelegram.org/?read=17488 (Hubble detections of more fragments, sadly no pictures included).

Looks a good person (@…) made a mirror of the support website (with a UI that's amazing and every manufacturer should take note), so at least I found the drivers. https://toshiba-mirror.depau.gay/product/?mid=1073769759

An international group is organizing an observing campaign through the Citizen Science Working Group of the #LUMIO mission: LUMIO is an ESA space mission to observe lunar #impact flashes (LIFs) from space, on the lunar far side (#Geminid meteoroid stream, 13-15 Dec 2025. During the maximum of the stream, the number of visible impact flashes will be higher than during non-shower times, therefore there is a good chance of detecting at least some impact flashes.
Observations can be made using moderately-sized telescopes and a video camera. On the website https://lif.mi.imati.cnr.it/home_page.php there are now a recording of a thorough talk about the project and its slides at https://lif.mi.imati.cnr.it/open_item_page.php?item_idk=LDB-000000001 and slides about the preferred analysis software ALFI at https://lif.mi.imati.cnr.it/open_item_page.php?item_idk=LDB-000000002 -if you want to join in the LGC please sign on by 21 November.

"For decades, reading instruction in American schools has been rooted in a flawed theory about how reading works, a theory that was debunked decades ago by cognitive scientists, yet remains deeply embedded in teaching practices and curriculum materials."
