Dayside Auroral Oval Expansion, Magnetic Flux Erosion, and Substorms
AGU 2024
spa-magnetospheric physics | 13 december 2024
Parker Para, Gerard J. Fasel, Owen Bradley, Dora C...
Magnetic flux is eroded from the dayside magnetosphere when the interplanetary magnetic field (IMF) turns southward. During this period, the dayside a...
