So the new #Kreutz #comet #MAPS is *still* following the constant rapid rise in brightness it has shown since discovery: a dumb extrapolation - cobs.si/analysis/?comet=2688&f - has it get 10,000-times brighter than the Sun at its extremely close perihelion which makes so sense at all, of course, physically.
"It must therefore be assumed that this increase in activity will level off significantly in the near future," writes fg-kometen.vdsastro.de/koj_202: "More likely are parameters m m0=12.0 mag / n=4 (or even lower), which would still result in a (very short-term) maximum brightness of about –9 mag (but this would probably still be significantly too bright) – always assuming that the comet survives its perihelion passage unscathed."
For other views see cbat.eps.harvard.edu/iau/cbet/ and arxiv.org/abs/2602.17626 and facebook.com/photo?fbid=102365 and cometografia.es/cometa-kreutz- - and the actual brightness is tracked at cobs.si/obs_list?id=2688 where it has reached ~11.5 mag. now.

„It’s a path puzzle. You draw a path that enters the grid at the top and exits at the bottom. Along the way, there are 50 sections, each following a different ruleset. Consecutive sections overlap by a few rows, creating short hybrid sections in between.”
This is amazing! The printable PDF-version is 17 pages! 🤯
