Development of the Scientific Educational Center ‘Chemistry of Molecules and Materials’

Scientific research laboratory ‘Solar - Terrestrial Relations’ was established in 2004 upon the decision of the Academic Board FGBOU VPO ‘Minin University’.

Until the year 2014 the laboratory ‘Solar - Terrestrial Relations’ functioned on a voluntary basis as a part of scientific and educational programs of the Academy of Sciences of Russia and the Ministry of Education and Science of the Russian Federation. Researches have been financed by grants RFFI, INTAS and by the Ministry of Education and Science of the Russian Federation within departmental special-purpose programs ‘Fundamental Researches of the higher school in terms of natural sciences and liberal arts’ and ‘Development of scientific potential of the higher school.’ The laboratory received a government order made by the Ministry of Education and Science named ‘Fundamental Consistencies of Solar Activity Influence on Magnetosphericly-Ionospheric Electromagnetic and Plasma Processes’.

Goals, objectives, profile of the laboratory

Goal: to establish fundamental consistencies of solar activity influence on magnetosphericly-ionospheric electromagnetic and plasma processes.

A magnetic cloud (A) of the solar wind causes an intensive geomagnetic storm (B) and the sequence of all polar events (substorm) (C): magnetic disturbance, energetic particle dropout, polar auroras. An intensive solar flare (D) changes parameters of the layers of t Earth’s atmosphere (E) by X-ray emissions. High intensity geophysical phenomena of natural (earthquakes, meteoroids, current systems) and artificial origin effect condition of the ionosphere (E) and geomagnetic field (F).
