Radiation Belt Response to Fast Reverse Shock at Geosynchronous Orbit
Ankush Bhaskar, David Sibeck, Shrikanth G. Kanekal +5
Fast reverse shocks (FRSs) cause the magnetosphere to expand, by contrast to the well-known compressions caused by the impact of fast forward shocks (FFS). Usually, FFSs are more g…
The intensity and evolution of the extreme storms in January 1938
Hisashi Hayakawa, Kentaro Hattori, Alexei A. Pevtsov +7
Major solar eruptions occasionally direct interplanetary coronal mass ejections (ICMEs) to Earth and cause significant geomagnetic storms and low-latitude aurorae. While single ext…
The Extreme Space Weather Event in February/March 1941
Hisashi Hayakawa, Sean P. Blake, Ankush Bhaskar +3
Given the infrequency of extreme geomagnetic storms, it is significant to note the concentration of three extreme geomagnetic storms in 1941, whose intensities ranked fourth, twelf…
Estimating Satellite Orbital Drag During Historical Magnetic Superstorms
Denny M. Oliveira, Eftyhia Zesta, Hisashi Hayakawa +1
Understanding extreme space weather events is of paramount importance in efforts to protect technological systems in space and on the ground. Particularly in the thermosphere, the…
A possible case of sporadic aurora observed at Rio de Janeiro
Denny M. Oliveira, Hisashi Hayakawa, Ankush Bhaskar +2
Being footprints of major magnetic storms and hence major solar eruptions, mid- to low-latitude aurorae have been one of the pathways to understand solar-terrestrial environments.…
Investigating the dynamics of COVID-19 pandemic in India under lockdown
Chintamani Pai, Ankush Bhaskar, Vaibhav Rawoot
In this paper, we investigate the ongoing dynamics of COVID-19 in India after its emergence in Wuhan, China in December 2019. We discuss the effect of nationwide lockdown implement…
