Geomagnetically Induced Currents (GICs) during Strong Geomagnetic Activity (Storms, Substorms, and Magnetic Pulsations) on 23-24 April 2023
Irina Despirak, Pavel Setsko, Andris Lubchich +5
We analyzed intense geomagnetically induced currents (GICs) recorded during a complex space weather event observed on 23-24 April 2023. Two geomagnetic storms characterized by SYM/…
Relativistic electron precipitation by EMIC waves: importance of nonlinear resonant effects
Veronika S. Grach, Anton V. Artemyev, Andrei G. Demekhov +7
Relativistic electron losses in Earth's radiation belts are usually attributed to electron resonant scattering by electromagnetic waves. One of the most important wave mode for suc…
Retrieval of Particle Size Distribution of Polar Stratospheric Clouds Based on Wide-Angle Color and Polarization Analysis
Oleg S. Ugolnikov, Boris V. Kozelov, Sergey V. Pilgaev +1
The intensive polar stratospheric vortex in the Arctic that shifted to northern Europe in the winter of 2019-2020 caused low temperatures and the frequent occurrence of polar strat…
Detection of Molecular Scattering Field by Polarization Analysis of Sky Background During the Transitive Twilight and Temperature Measurements near the Stratopause
Oleg S. Ugolnikov, Igor A. Maslov, Boris V. Kozelov
The simplest version of the method of detection of single molecular scattering basing on the polarization measurements of the twilight sky background by all-sky cameras is consider…
Noctilucent Cloud Particle Size Determination based on Multi-Wavelength All-Sky Analysis
Oleg S. Ugolnikov, Alexey A. Galkin, Sergey V. Pilgaev +1
The article deals with the analysis of color distribution in noctilucent clouds (NLC) in the sky based on multi-wavelength (RGB) CCD-photometry provided with the all-sky camera in…
Noctilucent Clouds Polarimetry: Twilight Measurements in a Wide Range of Scattering Angles
Oleg S. Ugolnikov, Igor A. Maslov, Boris V. Kozelov +1
Wide-field polarization measurements of the twilight sky background during the several nights with bright and extended noctilucent clouds in central and northern Russia in 2014 and…
