About this image

The Phase diagram includes data from sequences obtained on two nights, 3rd to 4th August 2020 and 6th to 7th August. The period is less than 8 hours so these observations were sufficient to almost cover the entire cycle - the first time I have succeeded in doing this. Timings of both primary and secondary minima were obtained and submitted to the Mt Suhora Observatory website of Krakow university.
