TV Cassiopeiae / TV Cas
Light curve and phase diagram of the EA type eclipsing binary TV Cassiopeiae / TV Cas. These were constructed from photometry of 45 images taken with the Bradford Robotic Telescope Cluster Camera (BRT) between 2014 September 3 and 2016 October 1. The images were taken using a tri-colour green filter.

Min II is slightly later than phase 0.5 in this phase diagram, but more observations are needed to accurately determine this phase shift - assuming it is real.
There is significant o-c activity with this star (Kreiner).
