Query: Anisotropy of fast-going processes in the Sun and new interaction in
  nature   The processing of the galactic coordinates of 3543 solar flares with a
magnitude of 2 or more has shown that the distribution of these fast-going
processes on the surface of the "nonrotating" Sun is irregular and non-random
what testifies that in the near-Sun space an anisotropy takes place which
practically coincides with that predicted and obtained in laboratory
experiments and caused by existence of the intergalactic vector potential ${\bf
A_g}$.
