SN 2023dbc (at the intersection of the white lines in the inset) is a fairly dim type II supernova in Messier 108, also known as the Surfboard Galaxy. Messier 108 is about 28 million light years from Earth. SN 2023dbc was discovered by the Zwicky Transient Facility on 13 March 2023. At the time of its discovery, the Supernova was magnitude 17.4 but dimmed to magnitude 19 by early April. SN 2023 dbc is red because of dust in Messier 108.
