Scientific paper

The period study of the eclipsing binary system GH Pegasi has been presented for the first time. A new period (P = 2d.556135) of GH Peg, based on all available times of minima, has been given. O-C diagrams of the system have also been presented for the first time, and the period changes present in the system have been analysed. The period shows changes around the years 1972 and 1981. The total period change in different portions of the O-C diagram, based on the corrected period, ranges from 5.2×10-6d to 7.0×10-5d. The photoelectric minima show sufficiently large scatter in the system.
