Space weather researches and particularly forecasting are impossible without existence of homogeneous experimental data for long term period. Catalogs of Solar Proton Events (SPE) provide information on one of significant parameters characterizing solar activity. The first SPE Catalogue (for 1955-1969) was created in 1975 by an international research group (with involvement of Soviet scientists) under the leadership of well-known solar physicists Z. Svestka & P.Simon. The next four Catalogues, published in 1983, 1990, 1998 and 2014, were created in the USSR and Russia by the team under the leadership of Yu.I. Logachev. Today a Catalogue of solar proton events as observed in the 24th cycle of solar activity (2008-2018) is creating. In the new Catalog the event maximum intensity of the >10 MeV protons on the Earth`s orbit was not less than 1 pfu =1 particle/(сm2ssr). The forthcoming Catalogue for the solar cycle 24, similarly to the Catalogue for the solar cycle 23, in addition to continuous calibrated series of energetic solar particle fluxes, will incorporate information on physical processes in particle sources on the Sun, accompanying phenomena in the X-ray and radio emissions and conditions in the near-Earth’s space as observed during each event under study. The solar cycle 24 differs significantly from the previous cycles in terms of frequency and characteristics of SPEs. Comparative study of SPE features in different solar cycles demands the homogeneous series of data. The Catalogue for the solar cycle 24, similarly to all previous Catalogues, will be placed in the World Data Center [http://www.wdcb.ru/stp/data/SPE/] and on the website of Space Monitoring Data Center of Moscow State University [http://smdc.sinp.msu.ru]. The SPE Catalogue for the solar cycle 23 is the only one placed in NOAA's National Centers for Environmental Information at the Space Weather section [https://www.ngdc.noaa.gov/stp/space-weather/interplanetary-data/solar-proton-events/documentation/]. Data of SPE Catalogs are needed not only for the helio- and geophysical researches and forecasting space weather. They are necessary for planning and ensuring radiation safety of spacecraft missions of various assignment, the main of which during the next decade will be the exploration of the Moon and preparation for human flights to Mars, where one of the main hazard is damage from solar and galactic rays.
