Steven Christe Space Sciences Laboratory, University of California, Berkeley, US Email: schriste (at) ssl.berkeley.edu Group 1 Contribution: We present a statistical survey of RHESSI microflares observed in hard X-rays (HXR) with simultaneous observations by the Nobeyama Radio Heliograph at 17 GHz and 34 GHz. These microflares were found using a new flare-finding algorithm designed to search the 6-12 keV count-rate when RHESSI\'s full sensitivity was available, in order to find the smallest events. Between March 2002 and March 2007, a total of ~25000 events are identified, of which ~8500 are also observed by Nobeyama at 17 and 34 GHz. We compare HXR and radio fluxes and analyze the relationship statistically. When the events are detected at both wavelengths, the relationship between the lightcurves falls into several classes. Radio and HXR images of a small selection of events are used to investigate the relative locations of the two emissions, and we discuss the physical conditions that affect the relationship between the HXR and radio emission.
