The water surrounded the station extend about 2 kms to the east, south and west of the observing tower. The observing dome is on the top of a 31-meter-high tower. The HSOS's telescope is characterized by its movable dome, which can be shifted away from the telescope when the seeing is favorable. The surrounding water reduces the temperature fluctuation at the telescope height, which is favorable for high resolution solar observing. The annual observation days are about 300. spase://naoc/person/GangHuaLin MetaData Contact spase://naoc/person/CuiZhao Team Member spase://naoc/person/XiaoYang Team Member Earth 40.4N 116.6E 62m spase://naoc/Instrument/HSOS/20_FDHT 20cm Full-Disc Ha Telescope 20_FDHT 2010-6-7T15:42:44Z The telescope's field of view is 32'*32', the spectral lines is 6562.81A, the temporal resolution is 1 sec, and the spatial resolution is better than 2''. spase://naoc/person/GangHuaLin General Contact spase://naoc/person/CuiZhao MetaData Contact spase://naoc/person/XiaoYang Team Member Unspecified spase://naoc/person/CuiZhao Cui Zhao National Stronomical Observatories, Chinese Academy of Sciences
