| Guidelines |
| The aim of the project is to obtain an empirical description of plasma behaviour in solar magnetic fields. The student will mainly deal with
- the measurement of the magnetic and velocity fields on the Sun - construction of the 3D picture of magnetic configuration and flow in the solar atmosphere in active regions - evolution of morphologic properties of magnetic regions |

| Preliminary scope of work in English |
| The Sun is a prototype star, which is also active. The solar activity is inherently connected to the creation, evolution, and destruction of magnetic fields in the convection zone of the Sun and in the solar atmosphere. The activity phenomena concentrate spatially in active regions -- complexes of activity with sunspots, prominences and occurrence of flares. The evolution of active regions is not completely understood, despite a long-time effort. The project aims to study some of the aspects of the enigmatic evolution of active regions throughout solar atmosphere by means of analysis and interpretation of solar observations. |
