TW Cancri / TW Cnc
Light curve of the EA type eclipsing binary TW Cancri / TW Cnc constructed from 81 unfiltered images taken with the Bradford Robotic Telescope (BRT) Cluster Camera between 10 October 2013 and 16 January 2016.
Below is a light curve generated from 77 images taken with the Open University COAST telescope (a 14 inch / 35cm Schmidt-Cassegrain) between 22 September 2017 and 11 March 2018 through a V filter.
Combining the above two sets of data generates the following light curve and phase diagram.. The BRT data is in black, the COAST data is in red.
The same phase diagram but in monochrome. for clarity;
The catalogue values for the period are 70.760 d (GCVS and AAVSO VSX) and 70.7602 d (Kreiner). There is little o-c activity evident (Kreiner).
