We present a multi-frequency and multi-instrument study of the 20 January 2005 event. We focus mainly on the complex radio signatures and their association with the active phenomena taking place: flares, CMEs, particle acceleration and magnetic restr

July 1, 2016 was the 100th anniversary of the birthday of the eminent Russian astrophysicist Iosif Samuilovich Shklovskii (1916–1985), who was a corresponding member of the USSR Academy of Sciences, a recipient of the Lenin Prize, and a member of t

We present an overview of the ground-level enhancement (GLE 72) of the cosmic-ray intensity associated with the recent powerful solar flare SOL2017-09-10 (X-ray class X8.9) based on the available neutron monitor (NM) network observations and on data
Appreciable hard X-ray (HXR) and gamma-ray emissions in the 0.04 to 150 MeV energy range associated with the 2003 October 29 solar flare (X10/3B) were observed at 20:38 to 20:58 UT by the SONG instrument onboard the CORONAS-F mission. To restore flar

The aim of this work is to determine the instant of acceleration at the Sun of protons responsible for the onset of the ground-level enhancements (GLEs). Using a set of data on peak soft X-ray intensity derivatives and hard X-ray and gamma radiation

We analyze experimental data on the temporal behavior of fluxes and energy spectra of hard solar X-ray and gamma radiation in the energy range of 0.015 to 300 MeV, obtained onboard the CORONAS-F satellite during a solar flare on August 25, 2001. Thes

The solar flare of 28 October 2003 (X17.2/4B) was recorded by the SONG instrument onboard the CORONAS-F satellite. A description of the SONG instrument, its in-orbit operation and the principal data reduction methods used to derive the flare gamma-ra

We consider the problem of optical detection of hazardous asteroids of 100–1000 m diameter on the Earth’s surface and in space. Appropriate instruments suitable for solving this problem are also considered.

Based on our analysis of the data fromthe global network of neutronmonitors for several events, we have found the times of the first increases in count rate at individual stations that precede the main solar cosmic-ray enhancement. The onset time of
