SN 1885A (also S Andromedae) was a supernova in the Andromeda Galaxy the only one seen in that galaxy so far by astronomers and the first ever noted outside the Milky Way. It is also known as Supernova 1885.It appears to have been seen first on August 17 1885 by French astronomer Ludovic Gully during a public star gazing event although Gully at that time thought it was scattered moonlight in his telescope and didnot follow up on this observation.
