Flare, 17 December 2006

These images show a system of coronal loops observed at the west limb of the Sun on 2006 December 17. Each image was taken simultaneously by EIS and represent the view of the region in different emission lines. Each emission line is formed at a distinctive temperature (indicated on the plots) and thus represent different temperature slices through the Sun's atmosphere. In the hottest line (Ca XVII 192.8) a bright 'knot' of emission is seen above the loops - a feature which is characteristic of intense solar flares.
