Astronomical Site Monitoring System of Lijiang Observatory
摘要
Abstract
Lijiang Observatory (also known as GMG) is at 100°01′48″ (E), 26°41′42″ (N), 3200 m above sea level, 40 km from Lijiang City. There are 8 telescopes: LiJiang 2.4-m Telescope (LJT), lijiang 1.8-m telescope, Sino-Thai 70-cm telescope (STT), Burst Optical Observer and Transient Exploring System 4 (BOOTES4), Yunnan-Hong Kong 45-cm Transit-ing Exoplanet Survey Telescope (TEST), 30-cm Automated DIMM, 9-cm Taiwan Automatic Telescope network 3 (TAT) and 10-cm Lijiang Coronagraph Telescope (LCT). Lijiang 2.4-m Telescope is a general-use optical telescope, which has 6 scientific instruments, different instruments can be changed in one minute by using the rapid instrument exchanging sys-tem. The instruments including: YFOSC (Yunnan Faint Object Spectrograph and Camera), PICCD (Princeton Instruments VersArray 1300B CCD Camera), LiJET (LiJiang Exoplant Tracker), CHILI (China Lijiang Integrated Field Unit), HiRES (fiber-fed High-Resolution Echelle Spectrograph), EMCCD, et al. The Astronomical Site Monitoring System (ASMS) of Lijiang Observatory is composed of astro-climatic station (ACS) and astro-monitoring station (AMS). The ACS includes meterological station, cloud sensor, brightness sensor and seeing monitor DIMM; the AMS includes the all-sky camera and video surveillance. Data acquisi-tion frequency of the ASMS of Lijiang Observatory is 1 min for a set of data, we analysed a full year's data, summing up the basic observation condition of Lijiang Observatory. The average temperature is 8℃, the average relative humidity is 71％, the average wind speed is 1.36 m/s, more than 80％ of the wind direction is southwest. The cloud amount is 3.2 in observing session, but 8.2 in non-observing session. The total observation time is about 2150 h, equal to 210 ～ 220 nights (if the observation time is longer than 3 h, it will be defined as an observation night). The average seeing is about 1.2″, in conclusion, Lijiang Observatory is one of the best optical astronomical sites in China, it has good seeing condition and low wind speed, very transparent atmosphere and nearly no light pollution. The best observation session is from October to next May.关键词
