Unusual Large-Scale Flaring Structure
Abstract
The Yohkoh/SXT data of August 21, 1999 displayed a spectacular transient brightening of a large-scale double whip-like structure extending through the corona to a length greater than 950 Mm. The transient originated at a relatively small middle-latitude soft X-ray bright point (XBP), which was also visible in the EUV range and had a small underlying Halpha plage with a bipolar magnetic configuration. The structure developed in the high-temperature (>2.5 MK) soft X-ray emission to both sides of the XBP during a few tens of minutes and could be recognized for about two hours. The observations suggest sudden energy release during the interaction of the magnetic structures of the XBP and the filament channel.
