M101 - Spiral Galaxy with Type IIL Supernova 2023ixf

M101 with SN 2023ixf (Ursa Major) SN 2023ixf (Type: IIL) discovered 2023-05-19.727 UT by Koichi Itagaki Alias: ZTF23aaklqou, AT2023iyi, AT2023jgd, AT2023jfz, PSN J14033858+5418421, PS23dij Discoverer Mag 14.9 (Clear filter)  ( Rochester Supernova site | TNS 2023ixf ) SN 2023ixf (Type: IIL) discovered 2023-05-19.727 UT by Koichi Itagaki at Mag 14.9 is located near M101's prominant star-forming region NGC 5461.  The supernova resulted from a exploding red supergiant and lies just 21 million light years away.  It's the closest core-collapse supernova to us since SN 1993J which lit up M81 (some 12 million ly away) in Spring 1993. The SN is designated of type II-L (L for 'linear') , which is characterised by a rapid rise to maximum brightness  followed by a slow and gradual decrease, that is thought to be brought about by ejection of the dead stars' outer hydrogen shell.
