We are monitoring radio states of GRS 1915+105 at 2-22 GHz with the RATAN-600 radio telescope (see also ATEL #1509). On 01 October 2010 (MJD 55470.66) we detected a very strong radio flare from the the black hole X-ray binary and microquasar GRS 1915+105. The spectrum of the detected optically thin synchrotron flare is well fitted by a power law: S_nu[mJy] = 958nu^-0.615[GHz] in 2-11 GHz range. The day before the radio fluxes were less 30 mJy at 5-11 GHz.
