Abstract

Following optical and near-infrared monitoring of XTE J1859+226 (IAUC #7279, #7284), HST/STIS observations were performed on Oct 18.10-18.38 spanning 112-1026nm. The UV spectrum shows broad (12000km/s FWZI) and deep Lyman alpha absorption, strong CIV 155nm emission (EW 1.1nm, 4000km/s FWZI) and weaker emission lines of CIII, NV, OIII, OIV, OV, SiIV and HeII. Sharp absorption lines of SiII, SiIII, MgII and other species also appear with possible interstellar origin.
