The Aragats Space Environment Center in Armenia provides real-time monitoring of cosmic particle fluxes. Neutron monitors operating at altitudes of 2000 m and 3200 m on Mt Aragats continuously gather data to detect possible abrupt enhancement of the count rates. Additional high precision detectors, measuring muon and electron fluxes, along with directional information have been put in operation on Mt Aragats in the summer of 2002. We plan to use this information to establish an early warning system against extreme solar energetic particle (SEP) events which pose danger to the satellite electronics and the space station crew. Solar ion and proton fluxes as measured by space-borne sensors on ACE and GOES satellites are used to derive expected arrival times of highest energy ions at 1 AU. The peaks in the time series detected by Aragats neutron monitors, coincided with these times, demonstrate the possibility of early detection of SEP events using the ground-based detectors.

Standard models of cosmic-ray origin link the space accelerators of our Galaxy to the supernova remnants (SNRs)-expanding shells driven by very fast blast waves, usually with gamma-ray pulsars near the morphological center. Energy spectra of fully stripped ions with charges from to can provide clues to the validity Z p 1 Z p 26 of the standard model. Unfortunately, smeared data from the extensive air shower experiments do not provide enough information for such ion "spectroscopy." Nonetheless, the measurement of energy spectra of two or three broad mass groups (so-called light, intermediate, and heavy) will allow us to prove or disprove the "rigiditydependent" acceleration. Recently, using multidimensional classification methods, the "all-particle" spectra from the MAKET-ANI experiment on Mount Aragats, in Armenia, was categorized into two distinct primary mass groups. We present, for the first time, the light and heavy nuclei spectra from the MAKET-ANI experiment.
