摘要

A 1993 May 14 flare was associated with both X-ray plasma ejection as hot plasmoid ejection and Ha filament eruption as cool plasma ejection. The flare proceeded through two stages according to a GOES soft X-ray observation. In the first stage, an X-ray plasma ejection, an Ha filament eruption, and a chain of pointlike Ha brightenings occurred. In the second stage, an Ha two-ribbon flare and an X-ray arcade structure were seen in Ha and soft X-ray images, respectively. The X-ray plasmoid and the eruptive Ha filament were in the same current sheet. The X-ray plasmoid started to rise with a speed of similar to 270 km s(-1) temporally after the Ha filament eruption. The top part of the X-ray plasmoid moved together with the eruptive filament. They were then decelerated before the main peak of the hard X-ray emission. The X-ray plasmoid was not a bloblike feature, as the eruptive Ha filament, but a loop structure. Our results indicate that the X-ray plasmoid was not the heated part of the Ha filament.
