On the solar white-light high resolution observations from space

Absolutely calibrated telescopic observations of the Sun in white-light with a sufficiently high space-time resolution from space have not been regularly performed. They are needed to resolve several important problems in the solar physics. Contributions of different morphological features to the total solar irradiance variations in the broad range of time scales from seconds up to many years can be definitely established in this manner for the first time. The quantitative role of the white-light emission in the overall energy balance of flares and eruptions on the Sun can be evaluated. More adequate theoretical models of corresponding processes on the Sun can be constructed using this new data.
