Filippov, B. P.
Examples of saddle structures observed in images of the Sun in Hα, soft X-ray (YOHKOH SXT), and ultraviolet (SOHO EIT) emission are presented. Since the plasma distribution is controlled by the magnetic field, the saddles testify to the presence of hyperbolic singularities in the magnetic field. Such singularities play an important role in the the…
