Figure 2: a) Trace 1600 Å image at 07:50:50 UT. b) Longitudinal magnetic map obtained by MDI onboard SOHO at 08:03:02 UT. The magnetic field scale is confined to -300 to 300 Gauss. The RHESSI HXR intensity image in 50-100 KeV energy band is co-aligned as red contour lines, the contour levels are 0.27, 0.4, 0.6 and 0.9 of maximum intensity. |

Figure 3: a) EIT 195 Å intensity image at 07:50:59 UT. The location of the polar coronal hole is indicated as ``C'' and the boundary of the filament channel is indicated as ``B''. The white rectangle indicates the area which is indicated in Fig. 5. b)-d) EIT 195 Å base difference images at 08:01:23 UT, 08:12:04 UT and 08:23:53 UT, the image at 07:50:59 UT has been subtracted. The arrows ``e1-e2'' point to the footpoints of the loop-like eruptive features (in b) and c)), ``L'' indicates the well defined loop hanging out of the solar limb (in c) and ``fe'' is the extreme extent point of the diffuse emission enhancements on the boundary of the polar coronal hole (in d)). |
