Efforts of UNIGRAZ for SOTERIA*  We currently build a new telescope (Ca-II K) at Kanzelhöhe Observatory in Austria. Multi-wavelength observations are of vital importance when studying initiation and propagation mechanisms of coronal mass ejections (CMEs) and flares.  We study the flare-CME relationship to obtain the available energy for propelling CMEs. How fast can a CME go and what limits its speed? How is the relation to the associated flaring process?  We study the directivity of CMEs close to the Sun and in interplanetary space. Only CMEs which are directed towards Earth may be harmful to our society.  We will construct a web-catalogue to search for solar events and features of interest. For scientists this will make it easier to investigate solar activity and to reach scientific goals. Temmer, Preiss, Veronig 2009 Temmer et al (under review) Kanzelhöhe Obs. *under WP3, WP6
