Study of the Long-Lasting Daytime Field-Aligned Irregularities in the Low-Latitude F-Region on 13 June 2022

Remote Sensing
The unusual daytime F-region Field-Aligned Irregularities (FAIs) were observed by the HCOPAR and the satellites at low latitudes on 13 June 2022. These irregularities survived from night-time to the following afternoon at 15:00 LT.

Small and meso-scale properties of a substorm onset auroral arc

, 2010
International audienceWe present small and meso-scale properties of a substorm onset arc observed simultaneously by the Reimei and THEMIS satellites together with ground-based observations by the THEMIS GBO system.

Magnetospheric and auroral activity during the April 18, 2002 sawtooth event. [PDF]

, 2006
We examine the 18 April 2002 sawtooth event. We find that the strong magnetic field dipolarizations observed in association with each tooth are not global in occurrence but are rather confined to the nightside.

Interplanetary magnetic field control of fast azimuthal flows in the nightside high-latitude ionosphere [PDF]

, 2008
SuperDARN radar data from both hemispheres for the interval January 1999 to November 2006 have been inspected for evidence of high-speed azimuthal flows in the nightside high-latitude ionosphere.
