The Quebec blackout on 13 March 1989, has made geomagnetically induced current (GIC)
research a socially important field of study. It is widely recognized that the effects of space …

Abstract Space weather events, including solar flares, coronal mass ejections, and
geomagnetic storms, have significant effects on various transportation systems. This review …

We report a new ionosphere phenomenon: Equatorial ionization anomaly (EIA) discontinuity
(EIAD), based on OI 135.6 nm radiance observations from the Global Observations of Limb …

Abstract Salient depletions (30%–40% of the reference values) were observed in the vertical
total electron content (VTEC) from the Global Navigation Satellite System (GNSS) network …

During geomagnetic storms, ionospheric storms can be driven by several mechanisms.
Observations performed using ground-and space-based instruments were used to reveal …

This study investigates the solar origins of August 26, 2018 geomagnetic storm and the
responses of the interplanetary medium and equatorial/low‐latitude ionosphere to it. We …

Abstract The 2015 St. Patrick's Day geomagnetic storm with SYM‐H value of− 233 nT is an
extreme space weather event in the current 24th solar cycle. In this work, we investigated the …

Abstract An Ionospheric Observational Network for Irregularity and Scintillation in East and
Southeast Asia (IONISE) is developed to identify and study the short‐term and fine‐scale …

This study investigates the response of equatorial and low latitude ionosphere during an
intense geomagnetic storm of 26 August 2018 (Dst min=− 206 nT) using the TEC …

Abstract The St. Patrick's Day storm of 17 March 2015 has a long‐lasting main phase with
the Dst reaching a minimum of− 223 nT. During the main phase, two strong prompt …
