Speckle interferometry of HIPPARCOS link stars. II
A second list is presented of stars that have been tested for theirsuitability as astrometric links between the Hipparcos satellite and theSpace Telescope. A speckle interferometer and autocorrelator were used,first on the 1.9-m telescope of the Mt. Stromlo and Siding SpringObservatories, and then, after discarding 16 stars showing evidence of abinary nature, on the Anglo-Australian 3.9-m telescope. Results aregiven for 123 stars. Combining the present list with the 1984 list, itis estimated that 29 percent of the original selection of 'cleanlooking' stars (on sky survey prints) are expected to be multiple at theresolution of the 3.9-m telescope, 0.03-0.7 arcsec.

Photoelectric observations of lunar occultations. XIII
Occultation observations made with the 0.76 m reflector at McDonaldObservatory are presented, for 319 events occurring between Jan. 15,1981 and Feb. 7, 1982. One table reports timings, and a second recordsobservations of 16 double stars, in particular, Nu Gem observationsreveal that the two close components are similar in color. This allowsan estimation of individual visible magnitudes (near 4.60 and 5.32)suggesting that the secondary is a late B-type main-sequence star. SAO158929 observations reveal systematic differences in angular diametervalues. Of the 16 observed double stars, 9 appear to be new discoveries,including SAO 93067, SAO 94595, and SAO 98770. A third table gives fullydarkened angular diameters for the stars SAO 158929, SAO 77516 Y Tau,and SAO 119035 Nu Vir.
