Lunar tides in the equatorial electrojet and in the ionosphere over the magnetic equator

An abnormally large value of the solar daily range of the horizontal magnetic intensity, H, found at stations within a few degrees from the magnetic equator has been ascribed due to eastward electric currents flowing in the lower ionosphere during the daylight hours and known as equatorial electrojet. A longitudinal effect in the strength of the electro jet with a maximum in the American zone has been shown by Rastogi
