“…The first comprehensive catalog of solar proton events including ground-based and satellite measurements, and associated solar phenomena, covered the 15-year period from 1955through 1969(Svestka and Simon, 1975. This was followed by a similar catalog for 1970-1979 (Akiniyan et al, 1982). The NOAA/USAF Space Environment Services Center in Boulder, Colorado, U.S.A. now maintains a current list of solar proton events which is published in Solar-Geophysical Data.…”

“…The catalog by Svestka and Simon (1975) supplemented by Shea and Smart (1977) were our basic sources for the years 1955-1969. Our basic sources for 1970-1979 were Shea and Smart (1979) and the catalog by Akiniyan et al (1982). Satellite measurements from the synchronous orbiting GOES spacecraft were used for the period 1976(Solar-Geophysical Data, 1988.…”

Solar proton events have been routinely detected by satellites since the 20th solar cycle; however, before that time only very major proton events were detected at the Earth. Even though the detection thresholds differed between the 19th and more recent cycles, more than 200 solar proton events with a flux of over 10 particles (cm z s ster)-~ above 10 MeV have been recorded at the Earth in the last three solar cycles. At least 15 50 of these events had protons with energies greater than 450 MeV detected at the Earth. Other than an increase in solar proton event occurrence with increasing solar cycle, no recognizable pattern could be identified between the occurrence of solar proton events and the solar cycle. The knowledge we have gained from the data acquired over the past 40 years illustrates the difficulty in extrapolating back in time to infer the number and intensity of major solar proton events at the Earth.

“…For model fitting we obtain equations for theoretical spectrum (1) and cross-spectrum (2) by using Feinman path integral technique [Frehlich R.G., 1987]. These equations give better results than equations obtained by using phase screen model and allow us to estimate the width of the solar wind stream.…”

“…The sequence of Catalogues provided 6 separate editions [1,2,3,4,5,6] covers the time span 1970÷2008 (the 20th÷23rd cycles of solar activity) and will be later supplemented by the 24th cycle and future cycles of solar activity. The data on solar proton events with generation of protons for which the maximum flux of protons with energy of Ер>10 MeV (million electron volts) exceeded Jp≥1 cm -2 ·s -1 ·sr -1 (pfu) were collected and systematized in these Catalogues.…”

The pre-flare structures in the corona are observed in UV spectral lines of ions FeXXIV, FeXXIII, FeXVIII several hours before big solar flares. During a flare the emission of the UV spectral lines in the corona are increased explosively. These phenomena can be used for prediction of solar cosmic rays. Information obtained from the worldwide neutron monitor network and measurements on GOES spacecraft demonstrates unambiguously that solar cosmic rays are generated in solar flares. These phenomena are well described by the solar flare electrodynamical model, created on the basis of the observational data and the numerical magnetohydrodynamic simulation using the initial and boundary conditions, taken from the active regions observation before the flare. It is impossible to exclude that the similar mechanism of particle acceleration is responsible for galactic cosmic rays generation. Now all published mechanisms of cosmic ray generation are based on unproven assumptions. These assumptions are not confirmed by longterm observations. With the modern concept of cosmic rays, a fundamentally important qu...

“…their intensity is equal to that outside the magnetosphere. The homogeneous data on SEPs with E > 10 MeV are available since 1964 and can be found in the Catalogues (Akiniyan et al, 1983;Bazilevskaya et al, 1986Bazilevskaya et al, , 1990Dodson et al, 1975;Sladkova et al, 1998). Shea and Smart (1990) extended the series of SEP events with >10 MeV protons back to 1955 using the polar ionospheric absorption records.…”
