We have recently realized a technique for measuring electron density fluctuations in the Sun's corona and found many interesting results, including: periodic fluctuations in electron column density; Coronal Mass Ejection (CME) magnetized electron clouds; turbulent spectra; power transfer from circular to linear polarization. The technique uses the propagation effects on a spacecraft downlink carrier. The goal of this proposal is to explore propagation effects in the coronae of Mira variable stars, using the OH maser lines on the far side of the star (i.e., the positive-velocity masers) as the signal. With their activity, Mira variables probably have much stronger atmospheric effects than the Sun. The masers have similar crucial qualititiies as the spacecraft carrier: high signal/noise, narrow lines, and polarization. This is completely unexplored territory in stars. If we are successful, we may open up a new observational field--the exploration and characterization of physical con
