TL;DR: In this article, the authors analyzed the variation in the width of the equatorial irregularity belt with season and solar activity and found that the irregularities causing scintillation around this location near the edge of the irregularity region are of two types with different occurrence patterns, namely, the mid-latitude type with maximum at the northern solstice and the Equinoctial maximum.
Abstract: Scintillation of the vhf signal at 136 MHz from the Japanese satellite ETS-2 obtained at Haringhata (Geographic lat.: 22°58'N, long.: 88°30'E) during 1977–78 shows maximum occurrence during northern summer solstice. There is considerable scintillation during equinoxes, in addition to the summer phenomenon, indicating that the irregularities causing scintillation around this location near the edge of the equatorial irregularity belt are of two types with different occurrence patterns, namely the mid-latitude type with maximum at the northern solstice and the equatorial type of equinoctial maximum. The equinoctial scintillation tends to increase with solar activity. The results are interpreted in terms of the variation in the width of the equatorial irregularity belt with season and solar activity.
