GSC 02259-00741
Light curve and phase diagram of semi-regular variable GSC 02259-00741 in Pegasus. This is my 21st discovery, confirmed on 19 April 2016.
Data from 84 unfiltered images taken with the Bradford Robotic Telescope Cluster Camera between 2013 July 8 and 2016 January 11.
Comparison stars UCAC4 616-000151 V=9.82 and UCAC4 614-000117 V=10.07
My observations have been combined with Northern Sky Variability Survey (NSVS) data, both of which were 'zero point adjusted' to derive a best fit period of 150.3 days.

A short run of observations were made using the Open University COAST telescope between 2018 December 26 and 2019 August 30. The 38 images were taken using a V filter and the resulting light curve is shown below.
