Abstract : During late August and early September, 1979, four interplanetary spacecraft passed through superior conjunction. Within a short time their radio signals all passed through the northern corona of the sun on the way to earth. This time period had been declared to be STIP Interval VII so that observers, using earth-bound instruments and instruments aboard other spacecraft, could acquire data to be correlated with measurements derived from the four interplanetary spacecraft signals. These conjunctions offered an excellent opportunity to observe the plasma within a few radii of the sun, at latitudes between 20 deg N and the Pole. In this first report on STIP Interval VII, we stress the type and extent of the measurements that were obtained from the spacecraft. Four types of signal processing and their resulting data are described.
