a) AIA 171 Å image with HMI magnetogram contours of positive (white) and negative (black) polarities. The contour levels are ±200 and ±500 gauss. b)–c) RHESSI X-ray contours (red: 6–12 keV, blue: 12–25 keV) overlaid on the AIA 304 and 1600 Å images. The contour levels are 85% and 95% of the peak intensity. d)–f) Observation of the flux rope in different AIA channels (304, 171, and 131 Å). S2, S3, S4, and S5 are the slices used to create the stack plots. F1 and F2 are the new footpoints of the flux rope. The oscillatory reconnection and associated flux rope formation with counterclockwise rotation is shown by a composite movie (AIA 171, 304, and 131 Å, bottom panels) available online.
