Short summary
This work examined the longitudinal variability of the equatorial electrojet (EEJ) and the occurrence of its counter electrojet (CEJ) using the available records of the horizontal component H of the geomagnetic field simultaneously recorded in the year 2009 along the magnetic equator in South American, African, and Philippine sectors. Our results indicate that the EEJ and CEJ undergo longitudinal variability. More ground observation data points are required in the African equatorial zone.
