The Catalog of solar flare events for the current 24th solar cycle groups together into one system a specification of all massif of flares with X-ray class equal to or exceeding M1 (10-5 Wm-2). The Catalog includes all solar flares of middle and large importance, their main characteristics, their manifestations in all range of electromagnetic waves, in the radiation of solar energetic particles (E>10 MeV), and in the observed dynamic phenomena. The Catalog is updated constantly with the flare events, and is an open document until the end of the current solar cycle.

The data are stored in the World Data Center for Solar-Terrestrial Physics, Moscow ( The data are freely accessible.

Database creation date: 2018; publication date: 2018.
