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.
