Quasi-periodic pulsations (QPPs) of gamma-ray emission with a period about 40 s are found in single loop X-class solar flare on 2005 January 1 at photon energies up to 2–6 MeV the SOlar Neutrons and Gamma-rays (SONG) experiment aboard CORONAS-F mission. The oscillations also be present microwave detected Nobeyama Radioheliograph, hard X-ray low energy channels RHESSI. Periodogram correlation analysis shows that QPPs microwave, X-ray, almost synchronous all observation bands. Analysis spatial...
Electromagnetic (radio, visible-light, UV, EUV, x-ray and gamma-ray) emission generated by solar stellar flares often contains pronounced quasi-periodic pulsations (QPPs). Physical mechanisms responsible for the generation of long-period QPP (with periods longer than 1 s) are likely to be associated with MHD processes. The observed modulation depths, anharmonicity suggest that they can linked some kind auto-oscillations, e.g. an oscillatory regime magnetic reconnection. Such regimes, both...
High-resolution radio observation of Nobeyama Radioheliograph at 17 and 34 GHz allowed studying the dynamics microwave brightness distribution along giant limb flaring loop in event 2002 August 24. It is found that on rising phase burst was highly asymmetric, with a strong maximum near southern footpoint (SFP) much weaker enhancements top (LT) northern footpoint. On decay phase, LT gradually became most bright. The similar are shown to happen for all major temporal subpeaks burst. Results...
Dynamics of the dayside magnetosphere and proton radiation belt was analyzed during unusual magnetic storm on 21 January 2005. We have found that from 1712 to 2400 UT, subsolar magnetopause continuously located inside geosynchronous orbit due strong compression. The compression be extremely 1846 2035 UT when dense plasma fast erupting filament produced solar wind dynamic pressure Pd peaked up >100 nPa and, in first time, upstream observed at almost 2 hours. Under extreme compression, outer L...
Moscow State University is developing a project for multi-satellite constellation intended the monitoring of space radiation. A number small satellites CubeSat format were launched into selected orbits crossing wide range magnetic drift shells. The primary scope operational near-Earth’s radiation environment, i.e., fluxes electrons and protons Earth’s belts energetic particles solar galactic origin. To date, there are four operating in near-Earth orbits, which deliver scientific telemetric...
The results of prediction geomagnetic indexes characterizing the state Earth's magnetosphere obtained with help artificial neural networks (ANN) for various horizons are presented. forecasts based on multivariate time series including values indices themselves, as well data about parameters solar wind and interplanetary magnetic field, during several latest hours.
Abstract This paper presents data on the simultaneous and complementary observations of gamma-ray burst (GRB) GRB 161017A for optical, X-ray, gamma wavelengths obtained by Russian multi-messenger Lomonosov space observatory supplemented additional from Swift satellite as well ground-based MASTER Global Robotic Net 10 m Gran Telescopio Canarias. Multifrequency spectra this very powerful explosion indicate that it originated at a distance billion light years Earth. Here, we present results...
We investigate the properties of a set solar flares originating from single active region (AR) that exhibit QPPs, and look for signs QPP periods relating to AR properties. The studied, best known as NOAA 12192, was unusually long-lived produced 181 flares. Data GOES, EVE, Fermi, Vernov NoRH observatories were used determine if QPPs present in For soft X-ray GOES EVE data, time derivative signal used. Power spectra series data (without any form detrending) inspected, with peak above 95%...
