A table of 81 distinctive solar radio outbursts occurring between January 1966 and July 1976 is presented. All of the bursts have the peak flux density U-shaped spectral signature found to be a reliable predictor of proton activity. These are the only events with this signature which occurred during the period. It has been confirmed that proton emission was indeed associated with 79 of the bursts: proton emission is probably for the remaining two events.
