In this paper, we present a statistical and case analysis of nighttime Pc3 pulsations observed from middle to equatorial latitudes during the year 2003. We found two groups pulsations. Pc3s first group are in fact nightside counterpart morning with large azimuthal scales slowly attenuating toward midnight. Such night signatures waves periods fast solar wind ( $$V>500\,\hbox {km/s}$$ ). The second type is locally generated They can be under moderate velocities. Maximal occurrence rates...
Abstract. A study is undertaken into parameters of the polar auroral and geomagnetic pulsations in frequency range 1–4 mHz (Pc5∕Pi3) during quiet intervals preceding substorms non-substorm background variations. Special attention paid to that occur under interplanetary magnetic field (IMF) conditions typical for undisturbed days (non-triggered substorms). The spectral observed luminosity as measured by a meridian scanning photometer (Svalbard) cap near boundary oval are studied compared with...
Abstract. The present case study is focused on fluctuations at ∼ 1.5 mHz observed open field lines in both of the polar caps ground-based geomagnetic data and electron concentration Northern Hemisphere ionosphere. Coherent pulsations with a relatively narrow narrowband-like spectra higher fraction transversal components total spectral power are also by Cluster satellites magnetotail magnetic field. Interestingly, started after over similar frequency range solar wind dynamic pressure...
In this paper, we study parameters of geomagnetic pulsations in the 1–4 mHz frequency range (Pc5/Pi3) magnetotail, utilizing data obtained by Cluster satellites at different levels fluctuations interplanetary magnetic field (IMF) and solar wind dynamic pressure 2016. Particular attention is given to conditions “zero” disturbance when amplitudes medium are smaller compared their typical values. Both under quiet disturbed conditions, waves spatial scales recorded, with occurrence rate...

Abstract—The magnetic effects of two similar underwater earthquakes with magnitudes 6.0 and 7.3, which occurred on March 16, 2022, were considered in [Adushkin et al., 2023]. According to the data INTERMAGNET observatories, these found be accompanied (with a delay ~55 min) by variations Earth’s field form train quasi-periodic oscillations an amplitude ~2–8 nT period ~30 min at distances ~210 ~3000 km from epicenter. It was suggested aforementioned study that this effect is caused...
Abstract. Our recent study (Yagova et al., 2017) shows that ultralow frequency (ULF) pulsations are seen in ground-based magnetic and luminosity data the polar cap for a few hours preceding isolated non-triggered substorms. Such characterised by high level of coherence. There might be two possible origins these pulsations: ULF disturbances solar wind or processes inside magnetosphere, which lead to substorm generation. In this case, first scenario should considered as trigger. To understand...
