Ejection of Heated Mass into a Helix-Like Structure from Active Region NOAA 7172 on May 21-27, 1992
Abstract
Following an extended soft X-ray flare on May 19, 1992, the magnetic structure related to the active region NOAA 7172 settled down into a roundish agitated active region with a helix-like structure extending in the south-west direction. Repeated ejections of heated mass into the helix-like structure took place from a point of contact between the helix-like structure and the agitated active region. We discuss two of these mass ejection events occurred on May 21--22, and May 26. The three-dimensional velocity in the event on May 26 could be examined through a coordinated use of the relevant part of the brightening of the images from the Soft X-ray Telescope (SXT) and the integrated intensity of the blue-wing profile of the S XV resonance line from the spatially non-resolving Bragg Crystal Spectrometer (BCS).
