Menagerie of loops: The images shown were obtained from the Soft X-ray Telescope (SXT) on the Yohkoh solar research spacecraft from October 3, 1991 to January 25, 1992. This particular selection is described in the article "The Yohkoh Mission for High-Energy Solar Physics", by L. Acton, et. al., Science vol. 258 , 23 Oct. 1992 pp. 618-625. The images here were selected to eemplify a variety of solar coronal feres seen in soft -rays.
A. Large Helmet type structure B. Arcade of -ray loops seen end-on C. Dynamic eruptive which generate a velocity of about 30km/sec D. One of many small symmetrical flaring loops seen by SXT.
