NGC 3277
NGC 3277 is a spiral galaxy in the constellation of Leo Minor. Its velocity with respect to the cosmic microwave background is, which corresponds to a Hubble distance of. However, five non-redshift measurements give a much farther mean distance of. It was discovered by German-British astronomer William Herschel on 11 April 1785.
NGC 3277 is a Seyfert II galaxy, i.e. it has a quasar-like nucleus with very high surface brightnesses whose spectra reveal strong, high-ionisation emission lines, but unlike quasars, the host galaxy is clearly detectable.
NGC 3277 is a member of the NGC 3254 group, which contains five galaxies, including NGC 3245A, NGC 3245, NGC 3254, and NGC 3265.
Supernova
One Supernova has been observed in NGC 3277:SN 2025coe was discovered by Kōichi Itagaki on 24 February 2025. Its light curves displayed multiple distinct peaks which is very rare among known calcium-rich supernovae, with only SN 2019ehk showing similar features. It had an exceptionally large projected physical offset of ~39.3 kpc from the galactic center, making it the most distant multi-peaked calcium-rich supernova ever discovered relative to its host galaxy. The progenitor system might have been ejected through dynamical interactions.
