Upper: GOES (1–8 and 0.5–4 Å) soft X-ray flux. Middle: RHESSI (3–6 and 25–50 keV) X-ray flux. The 25–50 keV curve has been scaled by 0.25. Lower: an example time-distance cut of the 131 Å loop oscillation. Times of different events are indicated. Blue solid line: approximate start of CME eruption at 12:13:21 UT. Dotted lines indicate the reference times of the oscillations, 12:13:36 UT for the 171 Å loops from White & Verwichte (2012) and 12:16:33 UT for the 131 Å loop.
