Flaring ribbons observed by the Rapid Oscillations in the Solar Atmosphere (ROSA) in Hα.

F-CHROMA is a project funded by the European Commission under Framework 7, that focusses on space-based and ground-based multi-mode, multi-wavelength study of solar flares. Solar flares are the most intense energy release events in the solar system, and – via their intense high energy radiation bursts and associated coronal mass ejections – a driving feature of space weather. Though solar flares have dramatic coronal manifestations, the bulk of the flare radiation comes from the denser lower atmosphere – or  chromosphere. This is the main location of flare energy dissipation and radiation, and the radiation can be analysed to provide many diagnostics of the energisation process.

The goals of F-CHROMA are to acquire, analyse and interpret ground- and space-based observational data of solar flares, test these against model predictions, and create an archive of solar flare observations and models, with major emphasis on their chromospheric aspects.
