Observations of solar-active regions with the Very Large Array (VLA) and with the Solar Maximum Mission (SMM) satellite are providing new insights to the origin and prediction of solar activity. This activity includes bursts or flares that can disrupt the tracking of satellites, distort communication systems, and interfere with high-flying aircraft. These bursts originate in coronal loops that are uniquely studied with the VLA (at 20 cm wavelength) and with the SMM (at x-ray wavelengths). The research summarized includes discussions of coronal diagnostics, solar-burst precursors, and energy buildup in coronal loops. Novel discoveries of coherent burst mechanisms on nearby active stars other than the sun. VLA observations of a solar-noise storm (at 92-cm wavelength) have resolved the sources of storm radiation for the first time. Future VLA observations with the new 92-cm system will provide new information about the unknown processes that trigger and continually excite solar noise storms, while also providing insights to the unknown triggering mechanisms for decimetric bursts and coronal mass ejections. This report includes reprints, preprints or abstracts of articles prepared under this grant.
