During the ongoing All Sky Automated Survey for SuperNovae (ASAS-SN or

"Assassin"), using data from the quadruple 14-cm "Cassius" 
telescope in Cerro Tololo, Chile, we discovered a new transient source:

Object        RA (J2000)    DEC (J2000)     Disc. UT Date   Disc. V mag

ASASSN-16bh   13:24:57.21   -27:56:10.9     2016-02-07.33   12.7 

ASASSN-16bh was discovered at V=12.7 in "Cassius" images taken on 2016-02-07.33,

but not present (V>17.4) in images taken on 2016-02-04.37. It was also
present 
in exposures taken on 2016-02-06.32 at V=12.7. At the position of the 
transient, Vizier reports a match to a B=20.3 USNO source and a GALEX source.

ASASSN-16bh is most likely a dwarf nova outburst. 
Follow-up observations are encouraged.
