Top, from left to right: TRACE 171 Å image taken at 03:27 UT, XRT image at 03:27 UT, XRT image at 01:01 UT, EIS raster image in Fe xii 195.12 Å obtained between 00:40 UT and 01:21 UT. The TRACE  171 Å, the XRT image at 03:27 UT and the EIS image have the TRACE 171 Å contour overplotted. The XRT image is overplotted with the −100, −50, 50 and 100 G contours of the magnetogram taken at 00:01:01 UT. Bottom, from left to right: TRACE 1550 Å image taken at 03:28 UT, SUMER O v 629.73 Å and S i 1256.49 Å raster images taken between 02:43 UT and 02:56 UT, EIS O v 192.90 Å raster taken from 00:40 to 01:21 UT. The SUMER Si i image is overplotted with the −100, −50, 50 and 100 G contours of the magnetogram taken at 00:01:01 UT. The rest of the images have the TRACE 1550 Å contour superimposed. All the images (top and bottom) are overplotted with the SUMER slit position. The positive polarity ais shown in white and the negative in black colours.
