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

"Assassin"), using data from the quadruple 14-cm "Brutus" telescope in

Haleakala, Hawaii, we discovered a new transient source:

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

ASASSN-15po   00:36:35.826  +21:51:25.75    2015-09-10.52   13.7 

ASASSN-15po was discovered at V=13.7 in "Brutus" images taken on 2015-09-10.52,

but not present (V>17.6) in images taken on 2015-09-08.47. At the position
of the transient, Vizier reports a match to a faint g=21.6 blue SDSS source.

Given the large amplitude of its outburst, this transient may be a 
WZ Sge-type dwarf nova. Follow-up observations are encouraged.

We thank LCOGT and its staff for their continued support of 
ASAS-SN. ASAS-SN is supported by NSF grant AST-1515927, the Mt. Cuba 
Astronomical Foundation, and the Center for Cosmology and 
AstroParticle Physics (CCAPP) at OSU. For more information about the
