Abstract
The mean velocities of coronal mass ejections (CMEs) detected in 2011–2012 are estimated from interplanetary-scintillation observations carried out with the Pushchino Big Scanning Antenna 111 MHz. The mean velocities are estimated based on the interval between the X-ray burst associated with the birth of the CME and the increase in the observed scintillations. The estimated mean CME velocity within the corona and the region probed by the scintillations at elongations from 40° to 50° is close to the mean velocity between the solar corona and the Earth. In half of the studied events, the estimated accuracy of the CME arrival time to the Earth is several hours. The CME velocities estimated from the delay between the X-ray bursts and the scintillation increase are significantly closer to the real velocities than the velocities estimated from the widths of the temporal spectra of the scintillations.
