The following are MPEG movies showing SOHO EIT/TRACE images (blue-white color scale) of the 2002/02/26 10:26 flare. Both EIT and TRACE observations were taken in the 195 A passband inluding the Fe XII line (1-2 MK) and possibly the Fe XXIV line (15-20 MK). RHESSI images (red-yellow color scale) are superimposed during the hard X-ray emission lasting two minutes. They display the 12 - 25 keV photon energy range. The time step of the movies is the RHESSI spin period of 4.35 seconds. The TRACE observations clearly show an ejection occurring with the flare. Later it develops into the shape of a bubble, which gets constricted at the bottom (best visible in Fig. 12, fourth image). It does not rise beyond TRACE's field of view, but becomes turbulent. The formation, development and constriction of the bubble is suggestive of a reconnection jet scenario speeding from the X-point located at coordinates (930,-220) in Fig. 12 (fourth image). The proposed scenario is depicted in Fig. 13. The energies in the various forms displayed in these images are discussed in the article by Saint-Hilaire & Benz in this volume.

  • The long version is the full version.
  • The short version lacks the initial EIT images, and has less frames.
