Abstract:
Expedition of Abastumani Astrophysical Observatory jointly with Brazilian colleagues carried out two experiments at Nim Ka Thana. The first experiment was obtaining color picture of solar corona by means of 3 meter expedition coronagraph. During the full phase of eclipse only one picture of corona was obtained. The second experiment was carried out using 1 meter telescope with beam splitter. It allowed us to obtain image of solar corona in red coronal line (6374Å) and in continuum simultaneously. The half width of interface filter in red line was 5Å and in continuum about 50Å. Four images in each other wavelength were obtained. Observational material has been developed and is of good quality.
