We present a summary of the Southampton/Valencia/Caltech/SAAO campaign for long‐term, multiwavelength monitoring of high mass x‐ray binaries. A number of sources have been observed in unusual states, including detailed studies of the Be/x‐ray transients X Persei (4U0352+309: disk loss state, 1988–1990), 3A1118‐616 (transient outburst, Jan. 1991), GX 1+4 (outburst Sept. 1993) and EXO2030+375 (periastron passsage, June 1993).
