Unique star. The mean brightness increased from 13.0m to 12.4m since 1889 to 1915, and fell to 12.8m in 1926. From 1895 to 1926 real shortperiodic oscillations with the amplitude about 0.4m. In 1928 the amplitude suddenly increased by almost 2m, but the magnitude in maximum remained unchanged. From 1928 to 1935 the light variations became periodic, the period increasing every year by 1d in accordance with the formula: Min = 2426087 + 15.933d*E + 0.0233d*E**2. In 1935 P = 21d. Since 1936 only small oscillations of brightness with a gradual increase of the mean magnitude from 14.3m to 13.9m B (1969). Photoelectric observations in 1968 - 69 reveal the light variations 12.33m - 12.72m V with possible periods 15.4d in 1968 and 45.3d in 1969. In 1973 12.28m - 12.58m V, Search (V0725-SGR):
