ASASSN-14jf (ATEL)

   The speed of decline between Oct. 20 and 22 looks slower
than in WZ Sge-type dwarf novae in the earliest stage.

During the ongoing All Sky Automated Survey for SuperNovae (ASAS-SN or
"Assassin"), using data from the double 14-cm "Cassius" telescope in Cerro
Tololo, Chile, we discovered a new transient source 
in the constellation of Pictor:

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

ASASSN-14jf   06:06:02.72   -60:39:41.0     2014-10-22.34      13.3 

ASASSN-14jf was discovered at V=13.3 in "Cassius" images taken on 2014-10-22.34,
and it is also detected in images taken on 2014-10-20.36 with V=13.1, but
it is not present (V>17.0) in images taken on 2014-10-13.28. At the position
of the transient, Vizier reports a match to a faint B=21.2 USNO-B1.0 source,
as well as a nearby GALEX NUV=20.9 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. For
