Track: SH.1.3
Strong signals of energetic neutrons associated with the solar flare of 7 September 2005 were detected by using the Solar Neutron Telescopes located at Mt. Chacaltaya in Bolivia and Mt. Sierra Negra in Mexico, Neutron Monitors located at Mt. Chacartaya and Mexico City. The observed profiles indicate a continuous emission of neutrons. In this paper, we present the results of combined anal ... More

In association with an X17.0 flare on 2005 September 7, strong neutral emissions were detected both in space and on the ground. In space, intense emissions of gamma-rays were registered by INTEGRAL and by RHESSI during the decay phase. Gamma-ray lines at 0.511, 2.2, 4.4, and 6.1 MeV were observed and there was evidence for pion-decay radiation. On the ground, relativistic neutrons were o ... More

It was surprising that Gigantic solar flares exceeding X-class occurred 10 times in September, 2005, because the activity of the Sun had already been in the declining period. More surprisingly, 4 X-class solar flares occurred in December, 2006, when the activity of the Sun was at the minimum. It is expected that some of these flares were accompanied by the acceleration of ions, which wou ... More

We have studied some characteristics of solar flares and surrounding medium (solar plasma) by means of 2.223 MeV line time profile of gamma-emission from neutron captures by hydrogen nuclei. It was composed the code with making allowance for the main processes of neutron interactions and deceleration in the solar atmosphere, character of neutron source, losses of neutrons and density model of ...

The solar flare of 20.01.2005 (class X7.1) was the biggest one in January 2005. It was started at 06:36 UT by GOES data, ended at 07:26 UT and the maximum of X-ray emission was at 07:01 UT. AVS-F apparatus (CORONAS-F) registered gamma-ray emission during rising phase of this flare in two energy bands: 0.1-20 MeV and 2-140 MeV. The highest gamma-ray energy was registered during this flare w ... More

The spectra and light curve of near a hundred Solar X-ray Flare events, which were observed by SZ2/XD in the energy band of 10-800 keV during 2001, have been investigated. The events covered from C to X-class flares, which are shown different characters of high energy photons emission. The results will be presented in this paper. The discussions will be made especially for 3 of the brigh ... More

We study the Sun as an extended source of gamma-ray emission, produced by inverse-Compton scattering of cosmic-ray electrons with the solar radiation. This emission contributes to the diffuse gamma-ray background even at large angular distances from the Sun. While this emission is expected to be readily detectable by the upcoming gamma-ray satellite GLAST, the situation for available E ... More

The hard X-ray (>150 keV, ACS SPI) emission during the X-class solar flares of 2006 December 5 and 6 lasted about 5 and 15 min respectively and the time profiles show several distinct peaks of about 1-2 min. If the time-profiles are plotted relatively the onset of 15.4 GHz radio emission, then the hard X-ray emission of the December 6 event would be delayed by 4 minutes in comparison wit ... More
