【 摘 要 】

We report on the radio properties of jets of the following microquasars, as determined from daily multi-frequency monitoring observations with the RATAN-600 radio telescope during 2010–2017: V404 Cyg, SS433, Cyg X-1, GRS1915+105 and LSI+61 ∘303. We have detected many giant flares from SS433, a powerful flare from V404 Cyg in June 2015, an active state of Cyg X-1 in 2017 and fifty periodic flares from LSI+61 ∘303. We describe the properties of massive ejections based on multi-band (radio, X-ray andγ -ray) studies. The general properties of the light curves are closely connected with the processes of jet formation in microquasars.
