NGC 4424

NGC 4424 is a spiral galaxy located in the equatorial constellation of Virgo. It was discovered February 27, 1865 by German astronomer Heinrich Louis d'Arrest. This galaxy is located at a distance of 13.5 million light years and is receding with a heliocentric radial velocity of 442 km/s. It has a morphological class of SB(s)a, which normally indicates a spiral galaxy with a barred structure (SB), no inner ring feature (s), and tightly-wound spiral arms (a). The galactic plane is inclined at an angle of 62° to the line of sight from the Earth. It is a likely member of the Virgo Cluster of galaxies.

Supernovae
Two supernovae have been observed in NGC 4424: • SN 1895A (type unknown, mag. 12.5) was discovered by Max Wolf on March 16, 1895. • SN 2012cg (Type Ia, mag. 16.9) was discovered by the LOSS program from images taken on May 17, 2012. It reached maximum light (mag. 11.9) nine days later The supernova reached a peak absolute magnitude of in the B (blue) band and synthesized of the radioactive isotope nickel-56. The available observations favor a merger of double degenerate progenitors as the source for the event. The proximity of the galaxy made this one of the best studied supernova explosions to date. ==References==
