As part of our on-going investigation of the charge-sign dependence in solar
modulation, we measured the cosmic ray positron abundance (~1GeV) on a
long duration balloon flight from Kiruna, Sweden to Victoria Island, Canada
during June 2006. Preliminary results from this flight will be presented and
compared to previous results.

The diurnal variations of GCR intensity observed by the ground NM stations
represent the anisotropic GCR flow at 1 AU. It is generally believed that the
variation of the local time of the GCR maximum intensity (phase) has 22-year
period of two sunspot cycles. However, there even exists doubt on such
anisotropy variation cycle. Those different interpretations come from the lack of
enough

A bimodal distribution around the sunspot cycle maximum was suggested to
exit for solar-terrestrial parameters (Storini et al., Adv. Space Res. 31, n° 4, 895-
900, 2003). The period between the two activity peaks was called the
Gnevyshev Gap by the Rome Cosmic Ray Group (Storini and Pase, GBRSC News
5, Special Issue, 255-258, 1995) and it is world-wide accepted by the scientific
communit

We calculate the temporal changes of the exponent g of the power law rigidity
R spectrum of the GCR isotropic intensity variations using neutron monitors
experimental data for four 11-year cycles of solar activity (1960–2002). The
temporal changes of the power law rigidity spectrum exponent g of the GCR
isotropic intensity variations are inversely correlated with the changes of the
GCR

The relationship of long-term cosmic ray modulation with solar activity parameters
such as sunspot group number, their average heliolatitude, tilt of current sheet, and
solar magnetic field strength is analyzed. The period of 1957 - present time is under
consideration. We have used cosmic ray data obtained in the atmosphere at polar and
middle latitudes and the neutron monitor data. It is sho

Long-term variations and short-term fluctuations of cosmic rays affect observations
on board long-lived space missions. We have developed a parameterization of Galactic Cosmic-Ray (GCR) fluxes
for various levels of solar modulation during opposite polarity periods on the basis of experimental data.
In spite of a general agreement among different results on protons, antiprotons, electrons and p

The Altcriss project aims perform long term measurement of the radiation environment
in different points of the International Space Station. To achieve this goal, it
employs an active silicon detector, Sileye-3/Alteino, to monitor nuclei up to Iron in
the energy range above 40 MeV/n. Both long term modulation of galactic cosmic rays
going toward solar minimum and solar particles events will
