There is a new Supernova in the sky! SN 2023ixf is a type II (core collapse) supernova located in the Pinwheel Galaxy (M101). It was first observed on 19 May 2023 by Koichi Itagaki and immediately classified as a type II supernova.Initial magnitude at discovery was 14.9. After discovery, the Zwicky Transient Facility project found a precovery image of the supernova at magnitude 15.87 two days before discovery. The supernova is about 21 million light-years from Earth and is expected to have left behind either a neutron star or black hole based on current stellar evolution models.
The supernova is located near a prominent HII region, NGC 5461, in an outer spiral arm of the bright galaxy.
By 22 May 2023 SN 2023ixf had brightened to about magnitude 11.It can be seen in telescopes as small as 114 mm (4.5 in)and should remain visually visible with backyard telescopes for a few months.The last supernova this close to Earth was SN 2014J in Messier 82, roughly 12 million light-years from Earth. The supernova started to fade on around 10 June 2023.
