Figure 2: The six raster scans taken in H2 and Si III, and the equivalent X-ray time-slice rasters. The X-ray rasters are constructed by stacking, for each SUMER observation, the cospatial XRT slices from the XRT Ti-poly images closest in time. The difference images are computed by subtracting the preceding XRT Ti-poly image. The plage H2 brightenings (labelled I, II, III) are circled in the H2, Si III, and top X-ray difference raster. The H2 contours are at  photons s-1 m-2 sr-1, and Si III contours are at 1.2 photons s-1 m-2 sr-1. All images have a linear intensity scale. The sun-x and sun-y co-ordinates are as in Fig. 3.

	Figure 4: SUMER spectral images and profiles of the H2 brightenings. The Si III intensity is reduced by a factor 20 compared to the rest of the spectrum, so that they can be displayed with the same scale. Each H2 spectrum is compared to the average plage spectrum, which has been scaled so that their continua at 1116 Å match.
