GCVS NOTE result

Min II 6.90. Min II - Min I = 0.55P. The shape of the light curve varies. There are probably long-period light oscillations: Min = 2442681.6 + 93.3d*E (A ~0.02m) [10051]. The period of X-ray pulses var: 282.8913s "(1975.5) [10125] "(1976.4), 282.838s (1976.9) [10127] "[10128] "(1981.0) [10129] (1983.2) [10078].
