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.
| Photoelectric observations of lunar occultations. XV
The last (or possibly penultimate) paper in a series on lunaroccultations presents observations of 404 phenomena, preceded by somegeneral remarks of a retrospective nature. The series of observationsbegan in 1968. Data for 20 doubles or suspected doubles are presented,ranked in order of certainty, with designation 3 representing thesurest. Thirteen of the cases refer to stars not previously noted asdoubles. Seven determinations of angular diameters are presented, ofwhich three have been previously observed.
