摘要: A recent 3D magnetic model of filament support (Aulanier and Demoulin, 1998) has shown that specific morphologies derived from the model, based on SOHO/MDI magnetograms, match quite well with observations a observed in Hα Ca ii lines German telescope VTT Tenerife 25 September 1996 et al., 1998, 1999a). Some predictions this concern channel. To continue comparison data, we have investigated same region ultraviolet by SOHO spectrometers SUMER CDS. The elongated EUV fine structures channel Si iv 1393.76 line similar orientations locations to features predicted Aulanier al. (1999a). These regions are near bases field which tangentially join photosphere so called 'bald patches' parts large arcades above In addition, consider Doppler shifts these compare them what might be expected structure. Our study also suggests very low opacity iv, lower than O v
