✦ Synopsis

From filament observations at centimeter and millimeter wavelengths it is shown that the transition layer between the dense, cool filamentary material and tbe ambient hot, rarified corona is rather thin, of the ordec of some hundred kilometers. Hence, the difference in the sizes of filaments in the radio and optical domains is of the order of 1000 km or 2", thus not detectable by tbe instruments so far used for observations of filaments.

Unique long-term visibility variations are detected when the quiet Sun is observed with interferometers operating at 8 mm and 11 cm wavelength with angular resolutions of -0.5'. Quasiperiodic fluctuations in fringe amplitude are observed with periods between 20 and 30 rain, and with amplitude nulls

Data from the recent gravity measurements by the Galileo mission are used to construct wide ranges of interior structure and composition models for the Galilean satellites of Jupiter. These models show that mantle densities of Io and Europa are consistent with an olivine-dominated mineralogy with th
