[1] Trushkin S., Goranskij V., Kotani T. A bright flaring of ss 433 // The Astronomer’s Telegram. — 2006. — no. 960. — P. 1–1. We report that the super-critical microquasar SS433 is the flaring state at radio waves and the optical band and would request for followup observations at all frequencies. In the monitoring program of microquasars with the RATAN-600 radio telescope (Trushkin et al., astro-ph/0611550), the flux densities at 1-22 GHz increased from a quiet optically thin synchrotron spectrum: S_nu[Jy] = 1.05*nu^{-0.54}[GHz] on 2006 Dec 6.48 (UT) to flaring one: S_nu[Jy] = 2.90*nu^{-0.43}[GHz] on 2006 Dec 8.47 (MJD54077.47) for the total range of 1-22 GHz. The CCD BVRcIj observations with the 50-cm Maksutov telescope and the 60-cm reflector of Crimean Station of SAI of Moscow U. from 2 to 10 Dec detected the associated optical flare: V=13.94 mag; Rc=12.52 mag on MJD 54075.691 and B=15.61 mag; V=13.41 mag; Rc=11.99 mag on MJD 54076.633. The last visual magnitude is one of the maximum values during last years. In the active state of SS433, successive flares are expected to occur with an average interval of 15.3 +/-7.3 days. This is a rare opportunity to observe transient jet eruption events from the source (Kotani et al. 2006, ApJ 637, 486).
