1 V1423 Cyg period determination Conner and Kalasek Conner, David S 2015-03-24 01:19 UTC Using images taken with the Bradford Robotic Telescope Cluster Camera (Tenerife) between 2012 July 13 and 2013 June 9, together with NSVS data, we derive a possible period of 133 days approximately. An unfiltered (clear) range of approximately 0.2 mag is apparent.
