4U 1658-48. Unusua1 X-ray system. Quasiperiodic optical variations (P ~20s) with total amplitude 40 percent, abrupt bursts on ~20 ms time scale leading to two-fold flux increase and light changes by 6m during less than two months were observed [C.Motch, S.A.Ilovaisky, IAU Circ N3609, 1981.]. Lx/Lopt = 3. |
