Supra-arcade downflows : ウィキペディア英語版 | Supra-arcade downflows
Supra-arcade downflows (SADs) are sunward-traveling plasma voids that are sometimes observed in the Sun’s outer atmosphere, or corona, during solar flares. In solar physics, an “arcade” refers to a bundle of coronal loops, and the prefix “supra” indicates that the downflows appear above flare arcades. They were first described in 1999 using the Soft X-ray Telescope (SXT) onboard the Yohkoh satellite. SADs are byproducts of the magnetic reconnection process that drives solar flares, but their precise cause remains unknown. == Observations ==
