The seminar holds regularly on Mondays or Tuesdays at 15:20
in the Conference Hall of P.K. Sternberg Astronomical Institute.
Head of the seminar: Prof. B.V. Somov,
Secretary: O.V. Dunin-Barkovskaya (e-mail: email@example.com)
The seminar considers the questions related to generation of magnetic fields in astrophysical plasmas, effect of the magnetic reconnection and particle acceleration in strong magnetic fields, the origin and propagation of cosmic rays, the flares and other non-stationary phenomena in the solar atmosphere and solar wind, Sun–Earth connections and physical processes in the heliosphere.

Forecast of the Space Weather Based on the National Observations of Solar Activity
We consider the prospects of development of the space weather forecast system based on the national ground-based facilities for observation of the solar activity. The forecast of space weather can be separated into three components: (1) prediction of the recurrent, gradually varying events, related to the topology of the large-scale magnetic field, (2) evaluation of the fluxes of UV and hard emission, and (3) observation of the quick events, such as the solar flares and eruptive processes, and forecast of their consequences in the Earth's orbit. To implement the forecast of recurrent events, the data of regular observations of the large-scale solar fields by the magnetographic telescopes for operational forecast STOP are efficiently employed now. To evaluate the hard radiation fluxes as well as to detect the eruptive events and evaluate their geoefficiency, data by the patrol optical spectrographic telescopes can be used. The patrol telescopes operate in automatic regime and enable us to register the corresponding processes with intervals about 1 min. To detect the eruptive processes, we suggest a method based on the difference of intensity in the wings of chromospheric spectral lines. In the present report, we shall consider the results of application of the observational complex of the Kislovodsk Mountain Station for forecasting the space weather.
