Scientific paper

To investigate coronal X-ray (≥ 6 keV) emission using RHESSI, we select long-duration (≥ 3 h) flares with completely or partially occulted footpoints. Flare footpoint sources dominate and thus obstruct the observation of coronal emission; short durations do not allow enough time for observation of various changes. We examine the location, morphology, size, height, and spectral characteristics in 20 long-duration flares seen with RHESSI whose footpoints are occulted by the solar limb to at most 30°. In 4 cases we see hard X-ray (≥ 20 keV) coronal sources; in the remaining cases hard X-ray emission comes from partially occulted footpoints only or the coronal emission is thermal.
