Effects on the ionosphere at Huancayo, Peru, of the solar eclipse, January 25, 1944

The results of the effects of a solar eclipse of magnitude 0.88 at Huancayo, Peru, on the various components of the E-, F1-, and F2-layers of the ionosphere are described. Minima in ion-density were observed for the E- and F1-layers near the time of maximum eclipse. A delayed effect on the decrease of F2-layer ion-density was observed. An effect on F2-layer ion-density, which may be attributed to a corpuscular eclipse, is described. (Other suggestions regarding this effect are given in a separate report by H. W. Wells and A. H. Shapley.) The results of signal-intensity variations, WWV, are also noted.
