Apparent Places of Fundamental Stars ... / Apparent Places of Fundamental Stars 2025

The annual publication Apparent Places of Fundamental Stars (APFS) contains the apparent places of 64 stars from the Sixth Catalogue of Fundamental Stars (FK6). The booklet also includes explanations and examples. Right Ascensions (RA) and Declinations (DEC) are given with respect to the true equator and equinox. The apparent places of 60 stars are listed for every tenth upper culmination. In the case of four pole stars the apparent places are listed for every upper culmination. A further table simplifies the computation of apparent and mean sidereal time.

The online version of this publication is hosted permanently and freely available (open access) by heiJOURNALS, the e-Journal platform of Heidelberg University Library.
