Spiral Galaxy NGC 6389 in Hercules

Dreyer's description in the New General Catalog (NGC):

Faint, small, irregular figure, easily resolvable.

Spiral Galaxy NGC 6389 has been the location of two supernovae. One was SN 1992ab, a type II supernova that peaked near 17th magnitude. More recently (March 2000) SN 2000m was another type II of similar magnitude. Based on the published red shift, (and a Hubble Constant of 62 Km/sec per Mpc) a rough distance estimate is 164 million light years, with a diameter of about 133,600 light years.
