The current state and future directions of modeling thermosphere density enhancements during extreme magnetic storms
Denny M. Oliveira, Eftyhia Zesta, Piyush M. Mehta +4
Satellites, crewed spacecraft and stations in low-Earth orbit (LEO) are very sensitive to atmospheric drag. A satellite's lifetime and orbital tracking become increasingly inaccura…
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 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.…
Satellite orbital drag during magnetic storms
Denny M. Oliveira, Eftyhia Zesta
We investigate satellite orbital drag effects at low-Earth orbit (LEO) associated with thermosphere heating during magnetic storms caused by coronal mass ejections. CHAllenge Mini-…
