ABSTRACT
In Feb 1997, during a major radio flare in Cyg X-3, a 120 milli-arcsecond radio jet, which exhibited relativistic (~0.9 c) expansion, was observed. Although Chandra would be unable to resolve such a jet, a high-resolution spectra taken during a major flare may contain Doppler shifted emission lines revealing the presence of an x-ray jet. Observations of Cyg X-3 during such a flare offers the very interesting possibility of studying the dynamics of jet formation and propagation through the study of emission lines with the high spectral resolution afforded by the HETG/ACIS SI configuration. The 20 ks length of the observation permits coverage over one complete 4.8 hour cycle. A second 20 ks observation 3 days later provides data for studying the spectral evolution that surely accompanies su
