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

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

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

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

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

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

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
