Report on the lunar ranging at McDonald Observatory for the period September 10, 1972 to December 5, 1972

Abstract

About 115 lunar range measurements were obtained during the four lunations between 16 May and 9 September, 1972. Poorer than average weather conditions greatly affected the entire system operation. Changes in the method of creating lunar range predictions and an attanpt to improve old calibration data were two of the few departures from relatively routine operation.
