Figure 5: Superposed epoch analysis of (a) red arc (139 events), (b) red+green arc (42 events), and (c) STEVE (26 events). The vertical dashed line at zero hour represents the time of detachment of arcs as detected in the optical data. The average values defined every 1-min for red arc, red+green arc, and STEVE are shown by red, green, and purple curve, respectively. The grey lines show the standard deviation.
