Supernova doesn't have an official designation yet, with the IAU's catalogs' last entry being M82's. The AAVSO doesn't have a record of it yet, but based on M82's speed-of-recognition, it should be available in a few hours to a day.

I like to find asteroids and galaxy mergers- but all galaxies are still fine to me.

Supernova officially noted as 2014L (Type Ic).

Current estimations range from magnitude 15.4 to 17.2, but will likely even out later
