High Velocity Doppler Shift Observations of 10 MK Flare Plasma
Abstract
SOHO/SUMER observations in the corona above limb active regions have detected high Doppler shifts at the time of flares in high temperature lines in three situations: 1) At CME onset as the active region loops disrupt; 2) At the top of a supra-arcade at the time of downflows; 3) In oscillating flare loops. The main aspects of each are given. Questions arising from the observations and their resolution by Solar-B are suggested.
