RADIO AND X-RAY-IMAGING OBSERVATIONS OF SOLAR-FLARES AND CORONAL TRANSIENTS

We present a review of selected studies based upon simultaneous radio and YI-ray observations of solar flares and coronal transients. We use primarily the observations made with large radio imaging instruments (VLA, BIMA, Nobeyama, and Nancay) along with Yohkoh/SXT and HXT and CG RO experiments. We review the recent work on millimeter imaging of sol ar flares, microwave and hard X-ray observations of footpoint emission from flaring loops, metric type IV continuum bursts, and coronal X-ra y structures. We discuss the recent studies on thermal and nonthermal processes in coronal transients such as XBP flares, coronal X-ray jets , and active region transient brightenings.
