NGC 7259 is a spiral galaxy approximately 66 million light-years away from Earth in the constellation of Piscis Austrinus.[1] It was discovered by John Herschel on September 28, 1834.[3]

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 Luminous blue variable (LBV) Supernova impostor.[4] During the following years several luminous outbursts were detected from the SN 2009ip.[5][4] In September 2012 SN 2009ip was classified as a young type IIn supernova.[6]
