On December 11, 1923, Edwin Hubble discovered a nova in the Andromeda galaxy. Novae occurring in our Milky Way's sister galaxy are not that uncommon. There have been over 800 novae detected in M31 in the last 100 years. Hubble's 1923 discovery became known as M31N 1923-12c, the third nova discovered in December of 1923.
Fast forward to January 21, 2012. K. Nishiyama and F. Kabashima report the discovery of a possible nova in M31 and it is given the preliminary designation, PNV J00423804+4108417. If this proves to be a new nova in M31 it will get the permanent designation M31N 2012-01b, the second novae discovered in January 2012.
