Comet R3 PanSTARRS at Perihelion

We’re one comet down, and one to go for spring season 2026. We recently wrote about prospects for sungrazer C/2026 A1 MAPS and comet C/2025 R3 Pan-STARRS in April 2026. While the bad news is, Comet A1...

The new #Kreutz #comet is now C/2026 A1 (MAPS): http://www.cbat.eps.harvard.edu/iau/cbet/005600/CBET005658.txt and https://www.spaceobs.com/en/Alain-Maury-s-Blog/The-discovery-of-comet-C-2026-A1-MAPS and https://www.minorplanetcenter.net/mpec/K26/K26BC9.html - whether it will reach and survive #perihelion is highly uncertain but there is hope as https://www.facebook.com/groups/227002358661288/posts/1670699484291561 and https://groups.io/g/comets-ml/topic/117373975#msg34667 explain. And if MAPS makes it to perihelion and is (very) bright then coronagraphs on the ground might be able to catch it against the inner corona as the following table - calculated with https://ssd.jpl.nasa.gov/horizons/app.html#/ - shows.
