Supernova[edit]
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]
