Abstract
AbstractThe fine structures of the corona are analized using SXR and WL eclipse pictures. The measurement of the finest features observed at the CFHT on July 11, 1991 is discussed. We call the attention to the 3D aspect of the magnetic structure which can be apprehended and analysed assuming the plasma is concentrated in thin curved sheets observed on eclipse WL pictures. More geometrical parameters can be deduced from the stereo-view based on the hypotheses of a rigid rotation. A preliminary 2.5D model calculation is put forward to explain the active region coronal rays. It is based on the assumption of ad hoc chromospheric current distribution and analytic calculations.
