Beschreibungen/Notizen

• From white-light photographs of solar granulation obtained with the SOUP instrument on Space Shuttle Flight STS-19 we have measured the motions of granules using local correlation tracking techniques. The granules are organized into larger-scale structures (mesogranular and supergranular) which exhibit outflow from upwellings, convergence into sinks, as well as significant vorticity. Magnetic fields follow these same flow patterns. We describe these velocity structures, and suggest that their effect on magnetic field structures may be important to the solar flare buildup process.
