NGC 4527 is a spiral galaxy in the constellation Virgo. It is a member of the M61 Group of galaxies, which is a member of the Virgo II Groups, a series of galaxies and galaxy clusters strung out from the southern edge of the Virgo Supercluster.[2]

Characteristics

NGC 4527 is an intermediate spiral galaxy similar to the Andromeda Galaxy[3] and is located at a distance not well determined, but usually is considered to be an outlying member of the Virgo Cluster of galaxies,[4] being placed within the subcluster known as S Cloud.[5]

Unlike the Andromeda Galaxy, NGC 4527 is also a starburst galaxy, with 2.5 billion solar masses of molecular hydrogen concentrated within its innermost regions.[6] However said starburst is still weak and seems to be on its earliest phases.[6]

Three supernovae have been observed in NGC 4527: SN 1915A (type unknown, mag. 15.5),[7][8] SN 1991T (type Ia-pec, mag. 13),[9] and SN 2004gn (type Ic, mag. 16.6).[10]
