Sudden enhancements of atmospherics (SEA) and, even more, sudden cosmic-noise absorptions (SCNA) due to flares recurring in the same area of an active region seem to follow similar trends of development, exhibited here in eight groups of events occurring in 1958. If flare X-radiation occurs during simple heating and relaxation of solar gases, its developmental character should be similar from flare to flare, even in different regions. However, flare X-ray development as manifested by SCNA's and SEA's is as characteristic of individual flaring regions as the flares themselves. A thermal model in which gases rapidly heat and then cool does not seem capable of explaining these variations. The conclusion is reached that the X-radiation represents the immediate response of the solar atmosphere to the presence of high-energy particles. Patterns of fine development may then recur as a result of the influences of persistent magnetic fields that control the particle motions.
