WHY STUDY THE SUN IN X-RAYS Solar corona is well seen in short wavelength radiation – studies of coronal heating problem Studies of triggering, evolution and spectroscopy of solar flares - the most energetic events in the Solar System. Determining coronal plasma physical parameters T, EM Improving models of solar chemical composition – element abundances Tstin plasma ionisation equlibrium Space weather
