【Abstract】 The general situation of site selection for Near-Earth Objects Telescope of Purple Mowtain Observatory is described. The observed results of the night sky brightness and seeing at the candidate site, the cloud cover, wind orientation and velocity, temperature and its variation in night, as well as relative humidity are given. It is shown that the astroclimatic conditions of Paoma Mountain in Xuyi County meet the requirements of 120cm Near- Earth Objects Telescope.更多还原
