RHESSI's increased sensitivity compared to previous instruments (100 times at 10 keV) and its ability to create high resolution images makes it ideal to study microflares. During the period of 2003 May 11 through 2003 May 13, RHESSI observed a series of microflares, eight of which occurred with temporally coincident interplanetary type III radio bursts, as observed by WIND (1-14 MHz). Statistically we would have expected one coincident event. These flares range from GOES class A1 to B1 above an average background of B1. Imaging shows that many of these flares originate from the same active region. For three of the flares TRACE 1600Å movies show similar geometric structures, with two bright spots spatially coincident with X-ray emission (3-15 keV) and jets leaving the flare site. A similar set of events was analyzed by Christe et al (SPD 2003). We present an investigation of the structure of these flares in order to determine why they are associated with type III bursts.
