GSC 02259-00970
Light curve and phase diagram of GSC 02259-00970. This was my 20th variable star discovery, confirmed on 29 March 2016.
This is a semi-regular variable in Andromeda with a period of 79 days.
It was discovered using Muniwin on 71 unfiltered images taken with the Cluster Camera of the Bradford Robotic Telescope between 2013 July 8 and 2016 January 11. The light curve and phase diagram were constructed using AIP4WIN photometry.
For more information see the AAVSO VSX.
A short run of observations were made using the Open University COAST telescope. The resulting light curve was generated from 20 images taken between 2018 December 25 and 2019 August 5. The images were taken using a V filter.
