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.
| Cloudcroft occulation summary. II - April 1980-December 1981
Lunar occultation observations obtained between April 1980 and December1981 at Cloudcroft Observatory are summarized. 24 of the 75 occulationsreported involve stars brighter than seventh magnitude. Although noangular diameter measurements are included, six observations arepresented which indicate duplicity; three of these stars are known orsuspected binaries, and the others are apparently new discoveries.Occultation observations of the Galilean satellites obtained on 16 July1980 and results from the Hyades passage of 19 September 1981 areincluded.
