Abstract
One-thousand eighty-eight observations of 947 binary star systems, obs erved by means of speckle interferometry with the 4 m telescope on Cer ro Tololo, are presented. These measurements, made during the period 1 989-1991, comprise the second installment of results stemming from the expansion of our speckle program to the southern hemisphere.
