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-14gz  17:23:25.95   +33:04:12.08      2014-09-09.26      14.2  

ASASSN-14gz was discovered in images obtained 2014 UT September 9.26 at
V~14.2 mag. We do not detect this object (V>16.5) in images taken on 2014
UT September 8.29 and before. There is a faint  and blue (g=21.9, r=21.8)
SDSS source 2" away, for which there is an <a href=http://skyserver.sdss3.org/dr9/en/tools/explore/obj.asp?id=1237671937119027282>archival
SDSS/BOSS emission-line spectrum</a> taken in quiescence classifying it
as a CV.  
Given the large amplitude of its outburst, ASASSN-14gz may be a WZ Sge-type
dwarf nova, caught very early. Follow-up observations are encouraged.

We thank LCOGT and its staff for their continued support of ASAS-SN. For
