IC 3622 also known as PGC 3793395, [1] is a large barred spiral galaxy [2] located in constellation Coma Berenices. [3] [4] It is located 980 million light-years from the Solar System and has a diameter of 175,000 light-years. [5] IC 3622 was discovered by Royal Harwood Frost on May 7, 1904. [6]
One supernova has been discovered in IC 3622 so far: PSN J12393328+1525520.
PSN J12393328+1525520
PSN J12393328+1525520 was discovered on February 22, 2013, by astronomers [7] on the behalf of the THU-NAOC Transient Survey (TNTS) [8] via a red filter Astrometry, [9] which the observation was performed on the ESO New Technology Telescope at La Silla. [7] It was located 12" east and 3" south of the nucleus, with a magnitude of 19.4. [10] The supernova was Type Ic. [10]
