TESIS:
scientific tasks
www.tesis.lebedev.ru
Scientific tasks:
 Investigation of the most dynamic processes
in the solar atmosphere, such as flares, coronal
mass ejections, dimmings etc.
Investigation of processes in far solar corona
(up to 4 solar radii) in EUV
 Study of evolution of large-scale long-life
coronal structures: active regions, coronal
loops, giant arcades, coronal holes and others.
Determination of the physical parameters
(electron temperature and density, differential
emission measure) of plasma of coronal
structures.

targets of observations
www.tesis.lebedev.ru
Targets of observations:
 Solar flares – their dynamics, energy
balance and physical characteristics
 Eruptive processes in the solar atmosphere –
triggers and methods of forecasting
 Coronal mass ejections – their formation and
dynamics
 Spectroscopy of coronal plasma in wide
temperature range
 Investigation of upper Earth atmosphere
