| Summary: | X-ray and H-alpha observations of an erupting filament and other observations of the associated flare on May 21, 1980 suggest that an erupting filament played a major role in the X-ray flare. While Antonucci et al. (1985) analyzed the May 21 flare as one of the best cases of chromospheric evaporation, the possible contribution from X-ray emitting erupting plasma has been ignored. It is that preheated plasma existed and may have contributed part of the blue-shifted X-ray emission observed in the Ca XIX line, which was formerly attributed solely to chromospheric evaporation. Thus it remains an open question - in two-ribbon flares in particular - just how important chromospheric evaporation is in flare dynamics. |
