The variable source of the plasma sheet during a geomagnetic storm [PDF]
Nature Communications, 2023 Both solar wind and ionospheric sources contribute to the magnetotail plasma sheet, but how their contribution changes during a geomagnetic storm is an open question.

Unexpected major geomagnetic storm caused by faint eruption of a solar trans-equatorial flux rope [PDF]
Nature CommunicationsSome geomagnetic storms’ solar origins are ambiguous, making them hard to predict. On March 23, 2023, a severe geomagnetic storm occurred, however, forecasts based on remote-sensing observations failed to predict it.

Mid-latitude ionosphere during two great geomagnetic storms
Annals of Geophysics, 1996 The ionospheric disturbances observed at many European ionosonde stations in association with the severe geomagnetic storms occurring on 19-20 December 1980 and 11-12 April 1981 were investigated by using the available ionospheric and geomagnetic data ...

The driving mechanisms of particle precipitation during the moderate geomagnetic storm of 7 January 2005 [PDF]
, 2007 International audienceThe arrival of an interplanetary coronal mass ejection (ICME) triggered a sudden storm commencement (SSC) at ~09:22 UT on the 7 January 2005. The ICME followed a quiet period in the solar wind and interplanetary magnetic field (IMF).

Ionospheric response to the corotating interaction region-driven geomagnetic storm of October 2002 [PDF]
, 2009 Unlike the geomagnetic storms produced by coronal mass ejections (CMEs), the storms generated by corotating interaction regions (CIRs) are not manifested by dramatic enhancements of the ring current. The CIR-driven storms are however capable of producing
