Galaxies NGC 4724, NGC 4726, and NGC 4727
Supernova 2003eg in Corvus

Supernova 2003eg:

• Discovered: May 17, 2003, by University of California at Berkeley's Katzman Automatic Imaging Telescope (LOTOSS).
• Magnitude 17.6 at discovery, and 16.25 in the Kopernik image.
• Type: II

Galaxies NGC 4724, NGC 4726, and NGC 4727 in the Constellation of Corvus are part of a galaxy group that includes IC 3799, IC 3819, IC 3822, IC 3824, IC 3825, IC 3827, IC 3831, and IC 3838. They all have nearly the same red shift, except for NGC 4727. Alhough its recession velocity is somewhat less, it seems to have a same distance as the surrounding galaxies.

NGC 4727 and NGC 4724 form an interacting pair similar to the more famous M-51. NGC 4727, the host of Supernova 2003 eg, is a Spiral Galaxy with a southern arm that links it with an 18th magnitude companion galaxy. There is perhaps one more dim companion (or background galaxy), in addition to Lenticular Galaxy NGC 4724. NGC 4727 was also the host of Supernova 1965 B.

NGC 4726 - Identification problem - Which galaxy is it?

NGC 4726 should be easy to identify since it is located exactly were its 19th Century discoverer, Tempel, said that it was! However, because of poor data recording by other 19th Cent. discoverers of galaxies in this area, it seems that the true identify of Tempel's discovery has been lost until just recently. Even modern catalogs (NGC 2000, PGC, TheSky, etc) mis-identify NGC 4726 as being the same galaxy as nearby NGC 4740 (also IC 3834). Recent work by Dr. Harold Corwin and others have properly recovered the true identity of Temple's discovery (NGC 4726) and it is the Lenticular Galaxy that shows in the upper right of the Kopernik image.

Classification: Lenticular Galaxy Note:        There is great confusion over the identification of this galaxy. Most databases do not properly identify it.
