This star was predicted (Krakow database) to have maximum eclipse and hence minimum brightness at 22:54 UT on 29 January 2018. My readings below show the minimum to be about an hour different.

Continuous 20s exposures were taken via SGPro through my Megrez 90 scope with an Atik 460EX mono camera with a Johnson V filter. The results were analysed with the free program Muniwin and the graph produced in Excel.
