Description
We present analysis of the long-term photometric data of the active giant OP And. Our
research is based on previously published photometric data, Hyparcos photometric
series and observations obtained at Belogradchik observatory, Bulgaria.
We provide Bayesian estimate photometric period of the star in the time interval
1983-1999 and compare it with the previous published ones. We have looked for its
changes and we are going to search a search for a possible long-term cycle.
