On the project

Cílem projektu je studium jemné struktury sluneční koróny, její dynamiky, časové proměnnosti a pohybů její plazmy z dat pořízených při úplných zatměních Slunce. Hlavní důraz je kladen na její nejnižší část a rychlé změny v ní. Budou nalezeny zdrojové plochy a další podklady k upřesnění modelů globálního koronálního magnetického pole. Porovnáme zpracovaná data bílé koróny získaná při úplných zatměních Slunce s družicovými daty (SOHO, TRACE a Hinode), porovnáme emisi v bílé koróně se strukturami nízké koróny v EUV oblasti a s modelem lokálního magnetického pole. Budeme analyzovat strukturu a chování vnitřní koróny v souvislosti s aktivními jevy v chromosféře a fotosféře. K analýze dat bude použita námi nově vyvinutá metoda vizualizace a matematického zpracování, která byla užita např. (Pasachoff et all., 2008) a pomocí níž byly získány unikátní údaje o stavu sluneční koróny, mj. i zjasňování a pohyb polárních paprsků.

Description in English
We plan to study faint solar coronal structures, their dynamics, temporal changes and plasma motions in corona observed during total solar eclipses. The main emphasis is devoted to the lowest parts and fast changes in solar corona. We plan to find sourcesurfaces and other parameters necessary for the coronal magnetic field specification. We will compare the processed white-light corona images from total solar eclipses with the satellite data (SOHO, TRACE and Hinode) and the white coronal emission with the low coronal EUV structures and with a model of local magnetic field. We will analyze the structure and behaviour of the inner corona in relation to chromospheric and photospheric active phenomena. The white-light corona pictures will be analyzed by an improved method of visualization and numerical image processing used e.g. by (Pasachoff et all., 2008), which allowed to obtain unique data about the solar corona as the polar coronal rays brightening and movement.
