The lunar tide influence on the equatorial electrojet (EEJ) gets intensified around noon, primarily
during new and full Moon periods. However, the longitudinal, seasonal and solar cycle variability in
the lunar tide’s influence on ionospheric current systems is not well understood yet. In order to
investigate this, 17 years (1998–2014) of extensive magnetometer observations at four longitudinal
sectors (western American, western and eastern African, and Asian) have been analyzed.
