NGC 4731

NGC 4731 is a barred spiral galaxy located near the Virgo Supercluster. To its celestial south lies NGC 4731A, a small irregular galaxy.^[2] Both galaxies feature high concentrations of neutral HI gas.^[3] It is theorized that its elongated arm structure could be related to gravitational interactions with a nearby galaxy, NGC 4967. It is a member of the NGC 4697 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.^[4]

On 2 April 1950 (the April 1950 lunar eclipse) it was occulted by the Moon during a Total Lunar Eclipse over Europe except the N and NE, Africa, Madagascar and the Indian Ocean. It happened again under those same conditions during the April 1996 lunar eclipse over the North Atlantic, Europe, N and NE Africa and Southwest Asia. It will next happen on 4 April 2080 over NE Siberia, NW North America, and the Pacific Ocean including Hawaii.^[5]: 160
