TL;DR: In this article, the authors used the Global Ultraviolet Imager (GUVI) data collected during evening at solar maximum to study the morphology of these so-called collapses, since the EIA collapse is shown to be linked to the suppression of equatorial plasma bubbles and scintillations.

TL;DR: In this article, the importance of electrodynamic drift near the magnetic equator in controlling nighttime ionospheric F region ionization and irregularities in the equatorial region was investigated.

TL;DR: The signal-to-noise ratio (SNR) of the L1 (1.6 GHz) transmission from GPS and GLONASS satellites has been recorded at Calcutta (22.58°N, 88.38°E geographic; 32°N magnetic dip, 17.35°N dip latitude) since 1999 by a stand-alone coarse acquisition (C/A) code Ashtec receiver.

TL;DR: In this paper, the authors used the diurnal maximum and integrated value (integrated from the time of onset of plasma influx to off-equatorial latitudes till local sunset) of the strength of the electrojet in the Indian longitude sector to calculate the vertical drift of the F-layer over the magnetic equator for the period August through October 2000.

TL;DR: The largest geomagnetic storm in solar cycle 24 occurred during March 17-18, 2015 where the main phase of the storm reached the negative minimum at 22:00 UT as discussed by the authors.
