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.
