    The Wave-Front Correction System for the Sunrise Balloon-Borne Solar Observatory

    This paper describes the wave-front correction system developed for the Sunrise balloon telescope, and it provides information about its in-flight performance. For the correction of low-order aberrations, a Corre...

    Dynamics of the solar granulation – On the Time Variation of the Granular Flow

    The emergence and evolution of large granules shows thegranular dynamics particularly well. We therefore investigate the time dependence of the convective flows within a regular and an exploding granule. The o...

    Shift-and-add reconstruction of solar granulation images

    To restore an atmospherically degraded image of solar granulation the shift-and-add (SAA) method is applied to its specklegrams. It is the first time, to the best of our knowledge, that such a technique has be...

    HEI10830Å in Solar Active Regions and its Correlat with Chromospheric Lines

    During the August 1993 International EFR Campaign, five active regions, which were at different phases of development, were observed at the German Vacuum Tower Telescope in Tenerife. We took filtergrams in Hα,...

    An attempt to compare the differential rotation of the Ca+-network with that of the photospheric plasma

    In this third paper of a series we report on results obtained from almost simultaneous observations of the differential rotation of the Ca+-chromosphere and the photospheric plasma. The observations (tracings of ...
