We present the results of multi-frequency observations of radio outbursts of the microquasar Cygnus X-3 in 2006 February and March with the Nobeyama 45-m telescope, the Nobeyama Millimeter Array, and the Yamaguchi 32-m telescope. Since the prediction of a flare by RATAN-600, the source was monitored from January27 (UT) with these radio telescopes. At the eighteenth day after the quench of activity, successive flares exceeding 1Jy were successfully observed. The time scale of the variability in the active phase is presumably shorter in higher frequency bands. We also present the result of a follow-up VLBI observation at 8.4GHz with the Japanese VLBI Network 2.6d after the first rise. AVLBI image exhibits a single core with a size of <8 mas (80AU). The observed image is almost stable, although the core shows a rapid variation in the flux density. No jet structure can be seen at a sensitivity of Tb (brightness temperature) = 7.5×105K. |
