Small LDE flare occurred at the end of filamental structure.

Time profiles of the maximum brightness temperatures in 17GHz images: black: full image, red: box1, yellow: box2 (see below). Data is plotted evely 10 minutes.

Full disk image at 17GHz (01:31:22UT).

Sequential images in the box1 (FOV is 490" x 490"). 17GHz beam size is also shown. Color is scaled by the maximum brightness in each image. Contour lines correspond to Tb = [1.e4, 5.e4] (K).
