Subject: [vsnet-alert] ASASSN-13bz - candidate CV

Hi everyone,

in ATel #5267 ASAS-SN reported the discovery on 2013 Aug 12.39 of 
ASASSN-13bz, a 16.1 mag CV candidate in the vicinity of M31. I obtained 
confirmation images on Aug 13.09 using a remotely-controlled 0.15-m 
telescope. The optical transient is clearly visible at the position
00:44:27.84 +43:42:41.4 (+/-0.2") J2000
2" away from the originally reported one. Its magnitudes are
JD(UT) 2456517.58941  V= 16.16 +/-0.09
JD(UT) 2456517.59172  B= 16.11 +/-0.03
B-V=-0.05 +/-0.10
calibrated using an AAVSO sequence star at 00:41:09.37 +43:24:20.9 J2000 
assuming B=14.583 +/-0.032, V=14.097 +/-0.030 (Henden USNO 1m photometry).

With best wishes,
Kirill Sokolovsky
