Drifting of the brightening from north (box1) to south (box2). Top row: AIA 94 Å middle row: AIA 171 Å bottom row: Temporal evolution of the normalized intensity in six AIA channels in box1 and box2. Three jets are marked with white arrows in panels (g), (i), and (l), respectively. Drifting of the hot material is quantified in the hot AIA 94 Å channel with the normalized intensity curves (blue curve in the bottom row).
