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)
