Illustration of a "streamer blowout" or "bugle" as observed in the low corona by Yohkoh/SXT. The event is the 24-Jan-92 event of Hiei et al. (GRL 20, 2,785, 1993). The plot at the bottom shows light curves from two regions of the corona, one (*) to the S of the developing arcade, and one (+) at its brightest point at about 12:00 UT. The image at the top shows the difference of two images (14:33 minus 06:01), with the zero contour overlaid. The voids left by the blowout are the regions S and N of the arcade, plus the areas at the top of the image on the disk. HSH, 3-Jun-92
