Abstract: We present metric radio observations of quasi-periodic emission from the solar corona in close association with a ``halo'' CME and an ``EIT wave'' phenomenon. The radio event lasted for about 60 s. Its mean periodicity was ~8.8 s. The estimated Alfvén speed in the corona was 1034 km s-1. The derived height of the source region of the observed quasi-periodic emission, and the magnetic field at the corresponding location (for emission in the fundamental mode) were ~ 0.23 Rsun and 6.3 G, respectively. The magnetic field for harmonic emission was found to be ~ 3.1 G.
