Solar jets, or transient, collimated brightenings, were first observed in soft x-rays by Yohkoh in the 1990's. These observations provided confirmation for the emerging flux model predicted by Heyvaerts and Shibata to describe reconnection in the corona. This model also predicts hard x-ray (HXR) emission during jet production, and recent RHESSI and HINODE observations appear to support this prediction. Unfortunately, projection effects make it difficult to determine whether HXR sources on the solar disk correspond to flare footpoints or to the jet itself. Observation of jets near or at the solar limb can mitigate projection effects and allow the jet geometry to be resolved.
Here, we present RHESSI observations of a partially occulted HXR flare that coincided with an EUV jet observed by TRACE on August 21, 2003. Comparisons between TRACE and RHESSI images and time profiles are used to illustrate several aspects of the emerging flux reconnection model, including the locations of outflow jets, post-reconnection flare loops, and HXR emission from the jet base. Radio data is used to provide corroborating evidence for the sources and timing of particle acceleration.
