GCN 26953) alert observation 50s after trigger time (Lipunov et al. GCN 26952) at MASTER-Tunka and 78s after trigger time at MASTER-IAC.MASTER auto-detection system found MASTER OT J001222.56+510700.3 at RA,Dec(2000) = 00h 12m 22.56s , +51d 07m 00s.3with m_OT=14.5 (unfiltered) at the first exposition (10s)with optical decay ,also detected by Swift UVOT (GCN 26953)Observation and reduction will be continued
