NGC 3190

NGC 3190 is a spiral galaxy with tightly wound arms and lying in the constellation Leo. It was discovered by William Herschel in 1784. NGC 3190 is member of Hickson 44 galaxy group, estimated at around 80 million light years away,^[2] and consisting of four galaxies in a tight group - NGC 3193 is fairly featureless, NGC 3187 is a dim but striking spiral galaxy and NGC 3185 has a barred spiral structure with an outer ring. It is also a member of the NGC 3190 Group of galaxies, which is a member of the Leo II Groups, a series of galaxies and galaxy clusters strung out from the right edge of the Virgo Supercluster.^[3]

Supernovae

Two supernovae have been observed in NGC 3190:

• SN 2002bo (type Ia, mag. 15.5) was co-discovered by Paulo Cacella and Yoji Hirose on 9 March 2002.^[4][5]
• SN 2002cv (type Ia-pec, mag. 19) was discovered by the Campo Imperatore Observatory on 9 May 2002.^[6][7] This Italian team detected the supernova while studying SN 2002bo, and both of these were visible at the same time.^[8][9]
