A combined optical and radio study of the solar ejection of 1982 January 22

The limb event 1982 Jan 22 with Type III + V and Type II bursts and Ha mass ejection is described. The bursts in short dm and cm waves are discussed in terms of the flux rate — time curve. For one main ejection, we find a magnetic field of ~12 G, a mass of ~10³⁸ electrons or ~10¹⁴g and an energy of 8 × 10²⁹ erg. We estimate the total energy of this event to be 10³⁰ erg.
