Short summary
Prague's Clementinum belongs to a few magnetic observatories that have been operational from the 1840s to the late 19th century. However, up to now these unique data from 1839 to 1871 have been available exclusively in printed yearbooks and only in raw instrumental units. In this paper, the data were analysed, transformed to physical units, and made available to the scientific community. Application of the data to the analysis of the geomagnetic disturbances in September 1839 is also shown.
