Exploding Loops

The images shown were obtained from the Soft the X-ray Telescope (SXT)
on the Yohkoh solar research spacecraft on 12 February 1992. All four
images include the sun's northwest limb curving from the top of the
image to the lower right. The large filamentary structure in the first
image ( 17:40 UT ) is observed in rapid transition in the next three
images taken at 18:52, 19:09, and 20:32. Uchida, et. al. in a paper
titled "Continual Expansion of the Active-Region Corona Observed by the
Yohkoh Soft X-Ray Telescope", Publ. Astron Soc. Japan v. 44, p L155
(1992) discuss the implication of finding many such expansions.
These images were enhanced to bring out the loop structure and the many
small bright spots are a result of this enhancement.
