This variable in Andromeda discovered by Anastasia Lazareva during the
International Research School - 2013 is in outburst for the first time
since the publication, see http://arxiv.org/abs/1307.6855 and
[vsnet-alert 16054].

MASTER OT J015016.17+375620.5 = 1RXS J015017.0+375614
  20130807.189 16.34C BRT
  20130909.161 16.77C BRT
  20130916.140 14.98C BRT

USNO-A2.0 1275-01091787 located 51" west of the variable (01 50 11.88
+37 56 12.9) was used as a reference star with R=14.1.

The long-term light curve is interesting. The variable spends most of
time near the middle of its variability range, around 16.5m, with a
few outbursts to 14.3-14.8m and occasional fadings to 19m. Orbital
period is unknown. The star is in the high state again right now, so
time-resolved photometry is strongly encouraged!
