HK Lac was observed at Konkoly Observatory between 1976-1981, the details of its story have been described in a previous paper (Olah, 1979).

The aim of this investigation is to give a possible description of the strong variations in the light curve of the star.

Searching for a more accurate period, it became obvious that the same period was not applicable to all the data. Therefore, a new period was derived for each different cycle by the Lafler-Kinman method. Unfortunately, due to the small number of data in the data sets these newly derived periods have an error of about 0.1 day.
