Fast Variability and Mini-Outbursts in the soft X-ray transient XTE J1859+226
The soft X-ray transient (SXT) XTE J1859+226 has been optically monitored from Tenerife using the IAC-80 and OGS 1m telescopes since its outburst on 1999 Oct 10 (see IAUC 7274, 7279). This R-band CCD photometry revealed a smooth decline of 0.017 mag/day for most of the next 8 months in parallel with that seen by the RXTE ASM, until two large ( ~2.5
