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
