Stack plots along the slices S2, S3, S4, and S5 using AIA 304 and 131 Å images. The Fermi GBM X-ray flux in the 6–12 keV channel is also included in panel c). The periodic rise of multiple reconnected loops is shown within a dashed ellipse (panel d)). The cotemporal X-ray bursts (panel c)) and strong chromospheric brightening in the AIA 304 Å channel (panel b)) indicate the particle acceleration and precipitation during the periodic rise of reconnecting loops.
