The Tokyo PMC catalog 90-93: Catalog of positions of 6649 stars observed in 1990 through 1993 with Tokyo photoelectric meridian circle
The sixth annual catalog of the Tokyo Photoelectric Meridian Circle(PMC) is presented for 6649 stars which were observed at least two timesin January 1990 through March 1993. The mean positions of the starsobserved are given in the catalog at the corresponding mean epochs ofobservations of individual stars. The coordinates of the catalog arebased on the FK5 system, and referred to the equinox and equator ofJ2000.0. The mean local deviations of the observed positions from theFK5 catalog positions are constructed for the basic FK5 stars to comparewith those of the Tokyo PMC Catalog 89 and preliminary Hipparcos resultsof H30.

Photoelectric photometry of chemically peculiar stars at the Catania astrophysical observatory. I - Observatory of HD 2453, HD 71866, HD 72968 and HD 126515
Photoelectric observations of four CP stars are presented which werecarried out from 1969 through 1975 at the Catania AstrophysicalObservatory in the UBV natural system. For the star HD 2453 a revisedvalue (546.87) of the period is derived from the magnetic field dataavailable in the literature which satisfies the photometricobservations. The periods of the stars HD 71866 and HD 72968 areconfirmed to be 6.80054 and 11.305 days, respectively. For the longperiod variable HD 126515 Preston's 130.0 days value, deduced from themagnetic field variations, is shown to be the period of the lightvariations too.
