On the variability of the solar diameterIn an attempt to elucidate the daily fluctuations seen in the 1980 drift time data (August 30-September 13) and to monitor the solar diameter for an interval as long as possible, visual drift timing observations were made on 46 consecutive days, from May 16 to June 30, 1981. A total of 2091 visual drift times (including 11 doubtful ones) wasWittmann, A. D. et al.

Design and operation of high performance space telescopesThe design and construction of an asteroid-borne giant optical telescope, and a multi-antenna ultra long baseline free-flying radio interferometer are described. The large scale and extreme tolerance of each instrument will require fabrication in space from nonterrestrial materials, and novel features of optical design. Details of the capabilitiesFrost, R. L. et al.

Structure in the 5 minute oscillations of integral sunlightThe discovery of structure in the 5 minute oscillations of the sun, integrated over the full disk, was reported by Claverie et al. (1979). This paper presents additional information on the discrete structure in the 5-minute velocity oscillation observed in integral sunlight. Measurements taken at Pic-du-Midi and Izana (on Tenerife) from 1976 toClaverie, A. et al.
