The given typical flux is the maximum flux in a strong outburst. Outbursts, e.g., in 1969/70 (3x), 1971, 1974, 1977/78, 1980 (2x), 1985, 1987, 1990, 1994, 1999, 2000. See, e.g.: Forman, Tananbaum & Jones (1976) Whitlock et al. (1989) Tamura et al. (1992) Bildsten et al. (1997) Negueruela et al. (1997) Heindl et al. (1999) Maybe there is an approximately 3 year recurrence time scale for strong bursts and an additional 6-9 months time scale (Whitlock et al., 1989; Negueruela et al., 2001b).
