Effects of the Geomagnetic Superstorms of 10–11 May 2024 and 7–11 October 2024 on the Ionosphere and Plasmasphere

Atmosphere
On 10 May 2024 at 17 h:07 UTC, the simultaneous arrival of several solar coronal mass ejections (CMEs) generated the strongest geomagnetic storm of the last twenty years, with a minimum Dst = −412 nT, usually referred to as the Mother’s Day event.

Dynamics of midlatitude light ion trough and plasmatails [PDF]

Light ion trough measurements near midnight made by the RF ion mass spectrometer on OGO-4 operating in the high resolution mode in Feb. 1968 reveal the existence of irregular structure on the low latitude side of the midlatitude trough.

A new model for plasmapause locations derived from IMAGE RPI and Van Allen Probes data

Journal of Space Weather and Space Climate
The outer boundary of the plasmasphere, the plasmapause, is characterized by a sharp electron density gradient that changes under varying space weather conditions.

The plasmapause revisited [PDF]

Saturation of the dc double probe instrument on Explorer 45 was used to identify the plasmapause. A data base was developed to statistically study the average position of the plasmapause over 14.5 hours of magnetic local time under differing magnetic ...

Plasmaspheric electron content

Geofísica Internacional, 1979
A pesar del abundante trabajo realizado sobre el problema del contenido electrónico plasmasférico y sobre flujos relevantes de plasmas fríos, existen solamente pocas determinaciones experimentales directas de estos conceptos.1. Sondeos ionosféricos (ionosondas terrestres y a bordo de satelites, mediciones de radar en experimentos de dispersión ...
