Abstract

In this paper, we investigated the response of ionospheric Total electron content (TEC) to the intense geomagnetic storm of 10^th - 11th May 2024 using 6 Global Navigation Satellite System (GNSS) stations: BAKE (Geog. Lat.64.33^o N; Geog. Lon. 96.02^o W), BELE (Geog. Lat. 1.41^o S; Geog. Lon. 48.46^o W), MBAR (Geog. Lat. 0.60^o S; Geog. Lon. 30.74^o E), SUTH (Geog. Lat. 32.38^o S; Geog. Lon. 20.81^o E), BJFS (Geog. Lat. 39.61^o N; Geo. Lon. 115.89^o E) and DUND (Geog. Lat. 45.88^o S; Geog. Lon.170.60^o E) situated over low, mid and high latitude regions. The GPS-TEC data was extracted, processed and used to plot vertical total electron content (VTEC) verses universal time (UT) from 8^th to 13^th May 2024 for each GNSS receiver station. A contour plot of TEC variation was also plotted for each station from 8^th to 13^th May 2024. The results showed TEC enhancing significantly at the beginning of the storm, during daytime at the geomagnetic equator, with the exception of MBAR, where TEC increased at night. This was attributed to the effect of prompt penetration of electric field (PPEF). A reduction in TEC was also noted on 11^th May 2024, during the recovery phase over all the GNSS receiver stations. This was attributed to the effect of the disturbance dynamo electric ﬁeld (DDEF) and composition change. The contour plots showed diurnal variation in TEC concentration over each GNSS receiver station. The TEC concentration however reduced during the storm period.
