Photoheliograms in Hα
on 35 mm B/W-film. Before 2000 a system with a film box was in operation in place of the current
High
Resolution Hα Imaging System. Image acquisition rate was1 image/4 min. Digital copies have been made
of the complete time series (1973 to 2000) with a 1 megapixel CCD camera.
Several times per day over-exposed images were taken to visualise the prominences.
