摘要
为分析南山站的光学观测环境条件,在南山观测站使用SBIG、SQM-LE等设备分别对大气视宁度、夜天光亮度和气象数据进行长期监测,在筛选和整理大量监测数据的基础上,进行逐月、逐年的统计和分析。结果显示,使用SBIG视宁度仪监测南山站年平均视宁度为1.74″,夜天光亮度为21.7 mag arcsec-2,年平均温度为3.4℃,年平均相对湿度为57.3%,风速主要分布区间为2~3 m/s,主要风向为西南风。上述参数表明,南山观测站的光学观测环境良好,可以满足中、小型望远镜的观测环境要求,测量结果可为其他光学台址起参考作用。
We introduced our approaches on monitoring the astronomical seeing, night sky brightness and weather condition by using the equipment of SBIG, SQM-LE at Nanshan Observatory. Statistical analysis and results are presented and discussed after removing the flawed data. Our analysis revealed an astronomical seeing of about 1.74＂, night sky brightness of 21.7mag arcsee^-2, average temperature of 3.4℃ and average relative humidity of 57.3% for Nanshan. The winds are in the range of 2-3m/s, most in south-east direction. The long-term observations support Nanshan Observatory to serve as an appropriate site to operate small and middle scale optical telescopes. Furthermore, our results provide comparison and reference information for other optical sites in China.
