Z Persei / Z Per
Light curve and phase diagram of the EA/SD eclipsing binary Z Persei / Z Per. These were constructed from photometry of 83 images taken with the Open University COAST telescope, between 2019 June 15 and 2023 April 2, using a V filter.
The catalogue periods for this star are variously given as 3.0563066d (GCVS) and 3.0562360d (AAVSO VSX) [accessed 2023 April 29].
Given the frequent poor weather at the site and technical issues affecting the COAST system I have now dropped this variable from my observing program in order to concentrate on long period eclipsing binaries.
