SN 2024vfo is a supernova discovered by Koichi Itagaki of Yamagata Prefecture in the UGC690 galaxy in the constellation Andromeda on September 11, 2024 (Japan time). Source.  Given the faintness which is estimated at Magnitude 18, this is impressive from the Seestar.  Its a type 2 II supernova.  A Type II supernova occurs when a massive star, between 8 and 50 times the Sun's mass, rapidly collapses and explodes. These supernovae are identified by hydrogen in their spectra and typically found in the spiral arms of galaxies or H II regions, but rarely in elliptical galaxies, which lack the young, massive stars required for such explosions.
