NGC 2775 (also known as Caldwell 48) is a spiral galaxy in the constellation Cancer. This galaxy has a bulge and multiple spiral arms, on which few HII regions can be detected, implying recent star formation. It was discovered by William Herschel in 1783. NGC 2775 is the most prominent galaxy in a small galaxy group known as NGC 2775 group, part of the Virgo Supercluster, along with our own Local Group. Other members of the NGC 2775 group include NGC 2777 and UGC 4781.〔 (【引用サイトリンク】 work=Atlas of the Universe )〕 SN1993z is the only supernova known to have occurred in NGC 2775 and was a Type Ia on Sept. 23rd that year at a magnitude of 13.9.〔(【引用サイトリンク】 work=IAU Central Bureau for Astronomical Telegrams )〕 By the 25th, spectra that was obtained showed that it had peaked four weeks earlier.〔(【引用サイトリンク】 work=IAU Central Bureau for Astronomical Telegrams )〕 ==Gallery== File:N2775ss.jpg|NGC 2775 imaged with a 32-inch telescope.
