Equatorial Electrojet & Total Electron Content Anomaly [PDF]

, 1979
44-46Total electron content equatorial anomaly is studied in relation to the electrojet strength using beacon signals from geostationary satellite ATS-6 recorded at Bombay Rajkot, Ahmedabad, Udaipur and Patiala. The anomaly is seen to maximize after 3-31

Effect of electrojet on low latitude radio wave scintillations [PDF]

, 1992
274-276Amplitude scintillation measurements recorded at Hyderabad (lat. 17.4°N, long. 78.4°E) at 136.1123 MHz from the geostationary satellite ETS-II have been utilized to understand the effect of electrojet on low latitude radio wave scintillations.

Responses of Field‐Aligned Currents and Equatorial Electrojet to Sudden Decrease of Solar Wind Dynamic Pressure During the March 2023 Geomagnetic Storm

Geophysical Research Letters
We present the observations of field‐aligned currents and the equatorial electrojet during the 23 March 2023 magnetic storm, focusing on the effect of the drastic decrease of the solar wind dynamic pressure occurred during the main phase.
