The observational follow-up of a theoretical study that suggested that the Venus cusp extension angle measured was dependent on the brightness of the terrestrial sky around it (RM-5386). This work presents a catalog of telescopic and photometric information on Venus obtained in 1969. Two specific celestial phenomena were investigated: inferior conjunction and greatest western elongation. The latter was observed simultaneously from two observatories some eleven degrees apart in longitude. Along with each photographic observation, many of which were in daylight or twilight, photometer readings of the sky near Venus and elsewhere were recorded. A major factor contributing to the success of the observational program was the development of a number of on-line JOSS computer programs. Attention is given to factors associated with the earth's atmosphere and with the characteristics of the observing equipment. 85 pp. (See also RM-6261.) (KB)
