SN 2023ixf - Type IIL Supernova (discovered 2023-05-19) in M101

M101 with SN 2023ixf (Ursa Major)
SN 2023ixf (Type: IIL) discovered 2023-05-19.727 UT by Koichi Itagaki

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.
(from Article "Summer's Super Supernova", AstNow Magazine, Sep 2023, pp 36-39)

Light Measurement of SN 2023ixf have been made from 2023-06-01 (T+13.3d) to 2024-04-17 (T+334.2d)
