Study of night time TEC depletion over Indian region

Abstract

Observations of night time total electron content depletions recorded over the Indian stations, Udaipur and Bengaluru, are presented. Udaipur is located near the crest of the equatorial ionization anomaly and Bengaluru is the near equatorial station. New features like location of plasma bubble over equator, north-west drift of the plasma bubble and time duration of sustainability of plasma bubble that produced depletion over low latitudes are being reported.
