Popis: The association of flare sprays, distortions of the overlying coronal structures and moving type IV radio bursts is a reasonable one and is well accepted despite the paucity of observational evidence. On 1972, August 12, there occurred a flare spray observed optically by both flare patrol and coronagraph instruments. A subsequent moving type IV radio burst was recorded by several instruments and distinct changes in the coronal brightness at 1.6 R ⊙ were measured. These observations combine to form one of the most complete sequences of measurements yet recorded covering the range from the chromosphere to about 6 R ⊙. The separate measurements are discussed and we show that they can be combined to form a relatively simple physical picture of the whole event.
