The partial solar eclipse could be seen in Freiburg the morning of 20 March 2015 on a clear sky day. Just in time for the first contact of the moon with the Sun, the Sun rose over the Schlossberg in Freiburg so that the images on the right could be taken from the terrace of the Kiepenheuer Institute.

In the scope of the dissertation, Sebastian Hoch will observe the chromosphere with spatial and temporal resolution, reaching the limit of the technically feasible. For this, the Broad Band Imager will be equipped with a new CCD camera, which is capable of recording at frame rates of 100 images per second at a detector size of 2560 x 2160 pixels. This high frame rate is needed to create speckle reconstructions with a cadence of merely a few seconds. The created reconstructions will be used to study the dynamics of the chromosphere in new temporal and spatial regimes.

The Center for Advanced Solar Spectro-polarimetric Data Analysis (CASSDA) at KIS is organizing a School for Solar Observers on Tenerife. The school will take place at the Observatorio del Teide on 20-25 April 2015 and is aimed at students and young postdocs who want to learn about solar ground-based high-resolution observations.

A new analysis method for solar surface magnetism. Standard algorithms for tracking small scale magnetic features suffer from ambiguities due to the intrinsic complexity of the feature interactions which are driven by photospheric convective motions.In his Ph.D. work, Andrei Gorobets will work on an alternative concept for tracking the evolution of photospheric magnetic features, which sidesteps the uncertainties of conventional direct feature tracking methods.
