Possible Nova in Centaurus

Dear friends,


Follows information from The Astronomer's Telegram #10387

During the ongoing All Sky Automated Survey for SuperNovae (ASAS-SN or "Assassin"), using data from the quadruple 14-cm "Cassius" telescope in CTIO, Chile, we detect a very bright, new transient source, most likely a classical nova, near the Galactic plane

Object RA (J2000) DEC (J2000) Disc. UT Date Disc. V mag
ASASSN-17gk 13:20:55.32 -63:42:18.5 2017-05-17.28 10.9
