A very close conjunction between Uranus and a Hipparcos star.
According to the most recent ephemerides, Uranus and its satellites willpass by two bright stars during Sept. 6 - 11, 2001. The two stars areamong Hipparcos Catalogue (star number 106829) and ACT Catalogue(AC2000: 2588165), respectively. During this period of time, theshortest angle distance between the Hipparcos star and Uranus will be5.90". The shortest one among the distances between the star and eachUranian primary satellite (Miranda, Ariel, Umbriel, Titania and Oberon)will be 2.08". The CCD observations on a telescope with a long focallength will be of great importance for this very close conjunctionphenomenon.
| 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.
| Appulses and occultations of SAO stars by Mercury - 1987-1995
While no readily observable occultations were found in the presentpredictions for 78 close approaches by Mercury to stars in theSmithsonian Astrophysical Observatory catalog (1966) over the periodJanuary 1, 1987-December 31, 1995, seven occultations of stars withvisual magnitudes of 7 or fainter are noted. These events are presentedwith a view to searches for material in the vicinity of Mercury, as wellas investigations requiring close, bright stars for the improvement ofground-based Mercury images.
