RHESSI contours overplotted on a TRACE background for the 60-s period between 13:58:00 and 13:59:00 UT. The RHESSI images are a 10-s time integration in the energy range 12–25 keV using the PIXON algorithm and detectors 3–8. The RHESSI contours for all images are at the same level at which the maximum X-ray amplitude is fixed at 4.2 photons cm² s¹ asec^-2 and each contour represents 10% intervals. The 1600  Å  TRACE images are at the central time of the associated RHESSI time integration.
