Supernova SN 2009ip

In 2009, a possible supernova was detected within the galaxy, and was designated SN 2009ip. Since the brightness faded in a matter of days, it was redesignated as a luminous blue variable (LBV) supernova impostor.[4] During the following years several luminous outbursts were detected from SN 2009ip.[5][4] In September 2012 SN 2009ip was classified as a young type IIn supernova.[6]
