摘要：We report the results of the 2006 April multi-wavelength campaign of SS 433, focusing on the
X-ray data taken with Suzaku. The campaign includes two Suzaku observations (in and out of
eclipse) and a large set of optical spectroscopy, optical/IR photometory, and radio observations.
The X-ray light curve in the out-of-eclipse phase had shown signicant variability, particularly
in the hard band above 5 keV. By analyzing the time sliced spectra of Suzaku, we detected rapid
variability of the Doppler shift of the jet (dz/dt 0.011/0.33 day), which is larger than those
expected from the precession and/or nodding motion. This may correspond to a .jitter. motion
observed for the rst time in X-rays. From the comparison of Doppler curves between optical and
X-ray bands, we determine the length of the optical jets to be 3.4(0.5)1014 cm.
