Abstract
This paper is an observational study of the equatorial anomaly during a period of declining solar activity. The anomaly is studied at two different longitudes, 75°W and 105°E. Data from both the topside and the bottomside of the F region are used. The topside data were obtained by the satellite Alouette 1. Seasonal and daily variations, longitude dependence, and geomagnetic storm‐time distortions of the anomaly are treated.Keywords
