摘要：We discuss the results of the radio studies of the X-ray binaries with relativistic jets. We carried
out a multi-frequency (1-30 GHz) daily monitoring of the radio flux variability of the microquasars
SS433, GRS1915+105, and Cyg X-3 with the RATAN-600 radio telescope during the
recent sets from 1 November 2006 to 31 August 2008. From December 2005 radio emission of
Cyg X-3 after four years relatively quiescent levels (100-200 mJy) dropped down to 20 mJy,
and then we detected a lot of bright radio flaring events (1-20 Jy) followed the very variable (from
0 to 0.5 crabs) 15-50 keV X-ray emission, which was monitored in the Swift/BAT ASM program.
Again from December 2007 to March 2008 we have daily measured almost quiescent fluxes from
Cyg X-3 but in April 2008 a bright radio flare with clear synchrotron self-absorptionwas detected.
We detected several bright short-term flares from GRS 1915+105 which could be associated with
active soft X-ray events. In intense measurements of SS433 fluxes (often mutually with X-ray and
optical observations) we detected massive ejections during powerful flares. We discuss the various
spectral and temporal characteristics of the light curves from the microquasars. Monitoring
of the flaring radio emission is a good tracer of jet activity X-ray binaries.
