Observational history
NGC 1255 was discovered by American astronomer Edward Emerson Barnard on August 30, 1883 with the 6-inch refractor at Vanderbilt University.[3][4] He described it as a "faint nebula, not large, pretty even in light. A faint star close p and slightly south probably involved. Star is s and f the nebula by about 30'".[3] American astronomer Ormond Stone made an independent discovery in 1886 with the 26" refractor at Leander McCormick Observatory, recording "4.1'x2.0', PA 315°".[3][4]
Supernovae
Two supernovae have been observed in NGC 1255:
- SN 1980O (Type II, mag. 17) was discovered by German astronomer Hans-Emil Schuster with the 1.0-m Schmidt telescope on October 30, 1980.[5][6][7] The supernova was located at the following coordinates: RA 03h 13m 27s, Dec -25° 44.50′ (J2000 epoch).[5][1] By December 30, 1980 the supernova had faded by about 4 magnitudes and showed strong P-Cyg-type profiles.[6]
- SN 2022ame (Type II, mag. 17.3), was discovered by Kōichi Itagaki on 27 January, 2022.[8]
