AB: Detectable signatures of magnetic reconnection, a possible source of solar coronal heating, aid in constraining flare energetics. Supra-arcade downflows (SADs), first detected during the Yohkoh mission, are an example of an observable consequence of magnetic flux tube reconnection. These sunward-traveling voids above arcade loops are consistent with outflows resulting in standard 3D reconnection models of solar flares. We have developed semi-automated detection software to detect downflows and analyze their trajectories, speeds, sizes, and magnetic flux in order to constrain parameters for flare modeling. We will present these measurements as observed primarily by SXT and TRACE supplemented with new XRT observations and discuss their implications.
