Eclipsing Binary star AD Andromeda

About this image

There was a near full Moon and the target star was of lowish altitude which may explain the scatter of the readings. Using the program Peranso with these and readings taken last year I determined the period of this binary to be 0.9862 days which agrees with the value given by aavso.

Strangely the time of the primary minimum was about an hour different from the Krakow prediction of 22:54 UT.
