Scientific paper

Optical positions are calculated for 26 active galaxies (mainly Markarian dn Arakelian objects), using the plate-measuring apparatus at Leiden Observatory on the O plates of the Palomar Sky Survey and applying AGK-3 data in the reductions. The results are presented in a table and have accuracy 0.5 arcsec; a comparison with the positions determined by Clements (1981, 1983) for 19 objects reveals a possible offset of -0.28 arcsec in the right-ascension determinations.
