Abstract Strong Thermal Emission Velocity Enhancement (STEVE) is a latitudinally narrow, purple‐band emission observed at subauroral latitudes. Stable Auroral Red (SAR) arcs characterized by major red emission, and red/green with both green emissions also occur Characteristics of magnetospheric source plasma electromagnetic fields these three types have not been fully understood because the limited conjugate observations between magnetosphere ground. In this study, we report 11 (2 STEVEs, 7...
The Solar-Terrestrial Environment Laboratory (STEL) induction magnetometer network has been developed to investigate the propagation characteristics of high-frequency geomagnetic pulsations in Pc1 frequency range (0.2–5 Hz). Five magnetometers were installed period 2005–2008 at Athabasca Canada, Magadan and Paratunka Far East Russia, Moshiri Sata Japan. sensitivity these is between 0.3 13 V/nT turnover frequencies 1.7–5.5 Hz. GPS time pulses are used for accurate triggering 64-Hz data...
Abstract We investigate pearl structures (amplitude modulations) of Pc1 pulsations simultaneously observed at Athabasca (ATH, 54.7°N, 246.7°E, L = 4.3) in Canada, Magadan (MGD, 60.1°N, 150.7°E, 2.6) Russia, and Moshiri (MOS, 44.4°N, 142.3°E, 1.5) Japan. From 6 years ground observations, from 2008 to 2013, we selected 84 events the longitudinally separated stations (ATH MGD) 370 latitudinally (MGD MOS), all with high coherence (>0.7) waveforms. calculated cross‐correlation coefficient...
Abstract We studied atmospheric gravity waves (AGWs) and nighttime medium‐scale traveling ionospheric disturbances (MSTIDs) using a three‐dimensional spectral analysis technique for airglow images at wavelengths of 557.7 nm (altitude: 90–100 km AGWs) 630.0 (200–300 MSTIDs), obtained from Athabasca (ATH), Canada (55°N, 247°E, 2005–2017), Magadan (MGD), Russia (60°N, 151°E, 2008–2017), over 10–13 years. The AGW propagation direction in summer was northward to northeastward ATH MGD with phase...
Abstract We have studied atmospheric gravity waves (AGWs) and nighttime medium‐scale traveling ionospheric disturbances (MSTIDs) by applying three‐dimensional spectral analysis technique to 557.7‐ 630.0‐nm airglow images at Shigaraki (SGK) (35°N, 136°E, 1999–2017) Rikubetsu (RIK) (44°N, 144°E, 1999–2017), Japan, Athabasca (ATH), Canada, (55°N, 247°E, 2005–2017), Magadan (MGD), Russia (60°N, 151°E, 2008–2017), focusing on their horizontal wavenumber spectra. For the AGWs in 557.7‐nm images,...
Abstract This paper reports two unique auroral features: postmidnight purple rays and global Pc1 geomagnetic pulsations, observed before the onset of corotating interaction region (CIR) storm 21 March 2017, at beginning first campaign new Particles Waves in Inner magnetosphere using Ground‐based network observation (PWING) longitudinal ground with Arase satellite.

The possibility of manifestation tropical cyclones in variations ionospheric parameters the zone far removed from disturbance source region has been studied. data frequency analysis by maximal observed frequencies (MOF) for oblique sounding (OS) signals were used. We revealed 1–5 h time intervals with higher oscillation energetics along Norilsk–Irkutsk, Magadan–Irkutsk, and Khabarovsk–Irkutsk paths (Eastern Siberia Far East Russia) during equinoctial periods (March, September 2005–2011),...
In this paper we study morphological peculiarities of wave-like ionospheric disturbances with period 1-2 hours and spatial dimentions more than 1000 kilometers. We use oblique-incidence sounding data obtained over Siberian region Russia during several monthly duration experiments in 2006-2010 years. Large-scale travelling recorded geomagnetically disturbed quiet conditions East are investigated. The connection between large-scale small-scale structures is mentioned.
In the given report results of complex radiophysical experimental measurements magnetospheric and ionospheric effects a solar eclipse in northeast Russia (March, 1988 June, 1990) are considered. For research materials ground vertical sounding, data about condition magnetic field record signals radio stations used. It is established, that reaction an ionosphere to passage lunar shadow shown increase minimal operating heights reflection F-layer (approximately on 20-25 km), reduction critical...
