“…A possible source is the magnetospheric (or polar) cusp along which magnetospheric plasma can penetrate into the ionosphere. Evidence from both ground [Bates, 1970;Oguti and Marubashi, 1966;Yevlashina and Yevlashin, 1971] and satellites [Heikkila et al, 1972] indicates that particle precipitation is centered near magnetic noon in latitudes essentially the same as the daytime part of the auroral oval [Feldstein, 1969]. Auroral data [Feldstein, 1964;Heikkila et al, 1972] show that under magnetically quiet conditions the zone is a few degrees wide and centered around 78 ø magnetic latitude.…”

The ionospheric storm model is based on a heat source located at magnetic noon on Feldstein's auroral oval. The rotation of the earth produces an apparent motion of the source that is greater than the speed of the disturbance. This gives rise to a wake or front that sweeps over the globe and determines the onset time of the negative phase, which results from a change in chemical composition. At the front focusing will occur, which accounts for the sudden drop in electron density (or content) sometimes observed. Calculated diurnal variations of maximum electron density and height are in general agreement with the positive and negative phases of storms.

“…Now two sources for the low-energy electrons are known. These particles cause an enhancement of F-region electron density (Oguti and Marubashi, 1966;Yevlashina and Yevlashin, 1971) and polar cap type A aurora (Sandford, 1968;Str6mman et al, 1971) around local noon.
