We have studied the 1999 soft X‐ray transient outburst of XTE J1859+226 at radio and X‐ray wavelengths. The event was characterized by strong variability in the disc, corona and jet – in particular, a number of radio flares (ejections) took place and seemed well‐correlated with hard X‐ray events. Apparently unusual for the canonical‘soft’ X‐ray transient, there was an initial period of low/hard state behaviour during the rise from quiescence but prior to the peak of the main outburst – we show that not only could this initial low/hard state be a ubiquitous feature of soft X‐ray transient outbursts, but also it could be extremely important in our study of outburst mechanisms.
