Description:
The proposed Hinode observations are in support of NuSTAR investigations of hot plasma and accelerated electrons in the high corona in partly occulted flares. Hard Xray observations of electron acceleration sites in the corona can investigate the mechanisms that accelerate particles up to the extraordinarily high energies observed. Previous instruments such as the RHESSI spacecraft have rarely been able to image faint sources in the corona due to insufficient sensitivity and constraints in imaging dynamic range caused by indirect imaging. The improved sensitivity of NuSTAR will allow the systematic observation of coronal acceleration sites, but due to the instrument?s limited count rate, this investigation will best be performed in occulted flares. In addition to coronal electron acceleration sites, other observations may include pseudostreamers and the study of escaping electron beams responsible for Type III radio emission.
