W Ursae Majoris / W UMa
Light curve and phase diagram of the EW type eclipsing binary W Ursae Majoris / W UMa. Constructed from photometry of 55 images taken with the Cluster Camera of the Bradford Robotic Telescope (BRT) between 2014 December 24 and 2016 January 16, using their 'green' filter.
The period is very close to 1/3 day, and the BRT automated 'scheduler' tended to prefer a similar direction in the sky to take images, hence the concentration of data on one of the peaks rather than more equally spaced observations.
