Abstract

We explore the hard X-ray source distributions of an C1. 1 flare occurred on 14 December 2007. Both Hinode/EIS and RHESSI observations are used. One of EIS rasters perfectly covers the double hard X-ray footpoints, where the EUV emission appears strong from the cool line of He ii (log T=4.7) to the hot line of Fe xvi (log T=6.4). We analyze RHESSI X-ray images at different energies and different times before the hard X-ray maximum. The results show a similar topology for the time-dependent source distribution (i. e. at 14:14:35 UT) as that for energy-dependent source distribution (i. e. at a given energy band of 6 - 9 keV) overlapped on EUV bright kernels, which seems to be consistent with the evaporation model. © 2010 Springer Science+Business Media B.V.
