Remark: The cycle of normal maxima 5d - 35d [09782, 03791]. Three different mean values of the mean cycle of supermaxima change each other being active at different time intervals: P1 = 161.5d; P2 = 203.9d; P3 = 248.1d (P = 201.7d) [09276]. Porb = 2.06d/N (N = 26, 27, 28) or 3.1h. Surrounded by a faint halo (28' diameter) of soft X-ray sources.
