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.
| Lunar occultation summary. III
Observations of 242 photoelectric lunar occultation events studied atErwin W. Fick Observatory are reported. Approximately one-fourth ofthese are reappearances. From each observation are estimated the minimummagnitude differences between the observed object and possibleundetected companions. Occultation observations are given of 23 starsbrighter than 6th mag, including Alpha Vir, Beta-1 Sco, Mu Gem, Xi-2Sgr, Zeta Tau, Lambda Gem, and Beta Cap.
