Science goals for missions to Jupiter in the early 1980's are reviewed and a case is made for the science community to play the key role in assigning relative priorities for these goals. A reference set of measurement requirements and their priorities is established and those high priority goals that are most demanding on spacecraft and mission

Doppler measurements, using the Capri magnetograph, of the latitudinal fine structure of the solar differential rotation have been carried out. The positions of the photospheric lines C I 5380.32 and Fe I 5364.88 have been simultaneously recorded. In contrast to Gilman's model (1972) which predicted an equatorial deceleration of the differential

Submillimeter observations made with a rapid-scanning interferometer during the solar eclipse of June 30, 1973 are reported. Reduction, correction, and plotting of the data is described, and the obtained results show that the spike can be identified with emission from chromospheric spicules. Models of spicules from optical wavelength data indicate
