Observations of the total solar eclipse on 22 July 2009 in China

The total solar eclipse on 22 July 2009 was observed by team of the Institute of Astronomy, Bulgarian Academy of Sciences, from the territory of China. The place for observations was situated at 300 km south-west of Shanghai, 900 m above the sea level, being close to the central line of totality. We used Fabry-Perot interferometer and CCD camera to obtain data for circumsolar dust sublimation. The interferograms of the sky during the eclipse were obtained in the line D of sodium. Using a B/W film and photo camera we also obtained images of the white-light solar corona for three polarized filter orientations and the degree of polarized corona was determined. The results are not consistent with other ones, obtained during the eclipses in the minimum of activity because of poor meteorological conditions and the observations through the dynamically changing cloudy layer.
