Abstract
Uncorrected central intensities of the Fraunhofer lines NaD1 and D2, Mgb1 and b2, and Hβ have been determined at a number of points along the S-W limb of the sun, from equator to pole, using photographic spectra taken at the Locarno station of the Göttingen Observatory. No significant pole-equator variation could be found in excess of the observational errors which are of the order of 2%.
