| Abstract: |
Sunward-flowing voids above post-coronal mass ejection flare arcades,
also known as supra-arcade downflows (SADs), have characteristics
consistent with post-reconnection magnetic flux tube
cross-sections. Applying semi-automatic detection and analysis
software to a large sample of flares using several instruments
(e.g., Hinode/XRT, Yohkoh/SXT, TRACE, and
SOHO/LASCO), we have estimated parameters such as speeds,
sizes, heights, magnetic flux, and relaxation energy associated with
SADs, which we interpret as reconnection outflows. We also present
speed and height measurements of shrinking loops in
comparison to the SAD observations. We briefly discuss these
measurements and what impact they have on reconnection models. |
