Monitoring fast solar chromospheric activity: the MeteoSpace project

Description

We present in this reference paper an instrumental project dedicated to the moni-toring of solar activity during solar cycle 25. It concerns the survey of fast evolv-ing chromospheric events implied in Space Weather, such as flares, coronal mass ejections, filament instabilities and Moreton waves. Coronal waves are produced by large flares around the solar maximum and propagate with chromospheric coun-terparts; they are rare, faint, difficult to observe, and for that reason, challenging. They require systematic observations with automatic, fast and multi-channel optical instruments. MeteoSpace is a high cadence telescope assembly specially designed for that purpose. The large amount of data will be freely available to the solar com-munity. We describe in details the optical design, the qualification tests and capa-bilities of the telescopes, and show how waves can be detected. MeteoSpace will be installed at Calern observatory (Côte d'Azur, 1270 m) and will be in full operation in 2023.
