A solar radio outburst with its different parts well seen on metric wavelengths is described. A stable source shows successively two kinds of emission before the flash-phase of the event, and a moving type IV burst (V ≃ 1000 km/s), initiated 1/4 solar radius high, is directly associated with a spray-type prominence. Parameters of this radiating source are discussed.

A type II burst seen on lower frequencies with a spectrograph (V ≃ 3200 km/s) seems to start after the flash phase. Two possible cases are considered for the generation of the shock-wave responsible for type II burst.
