Scientific paper

The plasma phenomena observed on board VEGA-1 and -2 spacecraft inside the cometary plasma region are summarized and their nature is discussed. The observed quasi-periodic modulation of the heavy ion density in this region could be explained by the development of the large-scale instability connected with the cyclotron resonance of ions with Alfven oscillations. The occurrence of 1 keV electrons during VEGA-2 flyby could be a signature of sporadic magnetospheric substorms in the cometary atmosphere. Plasma and magnetic field observations near VEGA-1 closest approach to the nucleus give evidence of super-Alfvenic cometary plasma acceleration initiated by interaction of two portions of different polarity magnetic fields.
