Kanzelhöhe Observatory (kso.ac.at) performs regular high-cadence full-disk observations of the
solar chromosphere in the H-alpha and CaIIK spectral lines as well as the solar photosphere in
white-light. In the frame of ESA's Space Situational Awareness (SSA) activities, a new system for
near real-time Halpha image provision through the SSA SWE portal (swe.ssa.esa.int) and for
automatic alerting of flares and erupting filaments is under development.
Image segmentation algorithms, based on optical flow image registration, for the automatic
detection of solar filaments in real time H-alpha images have been developed and implemented
at the Kanzelhöhe observing system. We present first results of this system with respect to the automatic
recognition and segmentation of filaments and filament eruptions on the Sun.
