    The Coimbra University spectroheliograph produces high-quality full-disc spectroheliograms in the lines Hα, Ca II K3, Ca II K1, and adjacent continua. The reduction software was extended to enable the measurement of velocity fields in Hα. We describe the instrument, the data processing, present the first results of the velocity measurements, and discuss the possibilities of improvement of their quality.
