    Abstract: It is a widely accepted fact that the quiet-time equatorial electrojet (EEJ) is a prominent narrow band of enhanced daytime eastward current flowing basically in the ionospheric E-region within ± 3° latitude of the dip equator. Studies have shown over the years that at least two magnetic stations are required to estimate the daytime variability str... Show More
