NGC 1288 is an intermediate barred spiral galaxy located about 196[3] million light years away in the constellation Fornax.[5] In the nineteenth century, English astronomer John Herschel described it as "very faint, large, round, very gradually little brighter middle." The morphological classification of SABc(rs)[4] indicates weak bar structure across the nucleus (SAB), an incomplete inner ring orbiting outside the bar (rs), and the multiple spiral arms are moderately wound (c).[7] The spiral arms branch at intervals of 120° at a radius of 30″ from the nucleus. The galaxy is most likely surrounded by a dark matter halo, giving it a mass-to-light ratio of 14 M/L.[3]

On July 17, 2006, a supernova with a magnitude of 16.1 was imaged in this galaxy from Pretoria, South Africa, at 12″ east and 2″ of the galactic core.[8] Designated SN 2006dr, it was determined to be a type Ia supernova.[9]
