Solar cosmic rays by the ground level observation: anisotropy

Solar cosmic rays during the extremely high ground level enhancement on 23 February 1956

The 23 February 1956 ground level enhancement of the solar cosmic ray intensity (GLE05) is the most famous among the proton events observed since 1942. But we do not have a great deal of information on this event due to the absence of solar wind and interplanetary magnetic field measurements at that time. Furthermore, there were no X-Ray or gamma observations and the information on the associat...

Ground Based Measurements of Galactic and Solar Cosmic Rays

EXECUTIVE SUMMARY The global network of ground based neutron monitors and muon telescopes constitutes a unique “instrument” in an armada of particle detection and measurement facilities now in space and to be deployed in the future. This network has a particle energy detection threshold of order 500 MeV, extending up to 50 GeV, with a full-sky field of view continuously making dozens of pointed...

Large Scale Cosmic Rays Anisotropy With IceCube

We report on a study of the anisotropy in the arrival direction of cosmic rays with a median energy per Cosmic Ray (CR) particle of ∼ 14 TeV using data from the IceCube detector. IceCube is a neutrino observatory at the geographical South Pole, when completed it will comprise 80 strings plus 6 additional strings for the low energy array Deep Core. The strings are deployed in the deep ice betwee...

Geomagnetic Field Eect over Azimuth Anisotropy of Cosmic Rays via Study of Primary Particles

Geomagnetic field is a one of the candidates for creation of anisotropy in azimuth distribution of extensive air showers over the entered cosmic rays to the atmosphere. Here we present the question: Is there any azimuth anisotropy flux in the upper level of the atmosphere due to the geomagnetic field over the entered cosmic-rays? The obtained answer is: yes. This investigation showed an agreeme...
