The Gannon Storm: Citizen science observations during the geomagnetic superstorm of 10 May 2024
Maxime Grandin, Emma Bruus, Vincent E. Ledvina +12
The 10 May 2024 geomagnetic storm, referred to as the Gannon Storm in this paper, was one of the most extreme to have occurred in over 20 years. In the era of smartphones and socia…
Auroral imaging with combined Suomi 100 nanosatellite and ground-based observations: A case study
Esa Kallio, Ari-Matti Harri, Olli Knuuttila +9
Auroras can be regarded as the most fascinating manifestation of space weather and they are continuously observed by ground-based and, nowadays more and more, also by space-based m…
Observations of Asymmetries in Ionospheric Return Flow During Different Levels of Geomagnetic Activity
J. P. Reistad, N. Østgaard, K. M. Laundal +7
It is known that the magnetic field of the Earth's closed magnetosphere can be highly displaced from the quiet-day configuration when interacting with the interplanetary magnetic f…
Scintillation and loss of signal lock from poleward moving auroral forms in the cusp ionosphere
K. Oksavik, C. van der Meeren, D. A. Lorentzen +2
We present two examples from the cusp ionosphere over Svalbard,where poleward moving auroral forms (PMAFs) are causing significant phase scintillation in signals from navigation sa…
An extensive survey of dayside diffuse aurora based on optical observations at Yellow River Station
De-Sheng Han, Xiang-Cai Chen, Jian-Jun Liu +6
By using 7 years optical auroral observations obtained at Yellow River Station (magnetic latitude N) at Ny-Alesund, Svalbard, we performed the first extensi…
Severe and localized GNSS scintillation at the poleward edge of the nightside auroral oval during intense substorm aurora
Christer van der Meeren, Kjellmar Oksavik, Dag A. Lorentzen +2
In this paper we study how GPS, GLONASS, and Galileo navigation signals are compromised by strong irregularities causing severe phase scintillation ( > 1) in the ni…
