SN 2009ip was a supernova discovered in 2009 in the spiral galaxy NGC 7259 in the constellation of Piscis Austrinus. [2] Since the brightness waned after days post-discovery, it was redesignated as Luminous blue variable (LBV) supernova impostor. [3]

During the following years several luminous outbursts were detected from the SN 2009ip. [4] [3] In September 2012 SN 2009ip was classified as a young type IIn supernova. [5]
