A supernova appears again in the Pinweel galaxy (M101), which reaches a luminous intensity of approx. 12.5 mag* and can be clearly pointed out in the photo (marker). The duration of this Supernova is amazing which has changed only a little in brightness for 28 days. SN 2023ixf was discovered on May 19 by the amateur astronomer Koichi Itagaki.
Already in 2011 a supernova took place in M101, which reached a luminous intensity between 9-10 mag*. M101 is located in the constellation of the Big Dipper and is approximately 21 million light years away. Astronomically speaking, this is as good as nearly in our neightbourhood.
*mag = > light magnitude: Up to mag +3-4 stars are visible nearby cities with the naked eye, in very dark areas the seeing limit can reach up to mag +6-7.
The more higher numerical value is given, the more weaker are the objects. E.g. - 4,7 mag, Venus glittering; - 1,0 Sirius, brightest star; +3,5 M31 Andromeda, pale shiny oval)
