SN 2009ip was a supernova discovered in 2009 in the spiral galaxy NGC 7259 in the constellation of Piscis Austrinus.[1] Since the brightness waned after days post-discovery, it was redesignated as Luminous blue variable (LBV) Supernova impostor.[2]

During the following years several luminous outbursts were detected from the SN 2009ip.[3][2] In September 2012 SN 2009ip was classified as a young type IIn supernova.[4]
