The Abnormal Quiet Days in SQ(H) in Mid and Low Latitudes Regions

Abstract

From the analysis and study of abnormal quiet days (AQDs) at mid and low latitudes locations, it was found that there is difference between the characteristics of phase variability Sq (H) of the low latitude locations. This suggests that the origin and cause of AQDs are of different sources in the two latitude regions. The AQDs events are independent of local time and could be of extra-terrestrial origin. The lunar contribution as seen from the analysis carried out has insignificant effects on the AQDs in both latitudes.
