The sky brightness and transparency in i-band at Dome A, Antarctica

The i-band observing conditions at Dome A on the Antarctic plateau have been investigated using data acquired during 2008 with the Chinese Small Telescope ARray (CSTAR). The sky brightness, atmospheric extinction, cloud coverage and auroral appearance are obtained from these images. The median sky b...

Description
Summary:The i-band observing conditions at Dome A on the Antarctic plateau have been investigated using data acquired during 2008 with the Chinese Small Telescope ARray (CSTAR). The sky brightness, atmospheric extinction, cloud coverage and auroral appearance are obtained from these images. The median sky brightness of moonless nights is about 20.46 mag arcsec −2 in the Sloan Digital Sky Survey (SDSS) i band magnitude system, and the median over all brightness in the Antarctic winter is about 19.81 mag arcsec −2. There were no thick clouds in 2008, and the weather is not so good as anticipated in June and July. We 1
