| 摘 要： | 对发生在世界时2013年10月21日19:29的313号小行星Chaldaea掩恒星HIP 47310进行了多站联测.对观测数据进行分析得出每个观测点的掩星时长,结合小行星轨道速度得出小行星剖面长度,用Occult 4软件对多站观测数据进行了椭圆拟合,最终得出该小行星的大小和形状以及轨道的偏差.同时,我们探讨了当今数码时代发动大量天文爱好者利用自身的业余观测器材取得较好的科研观测资料的可行性和优势. |

| Abstract: | On October 21 2013 universal time,multi-site observations of predicted occultation of star HIP 47310 by asteroid 313 Chaldaea were carried out at 1 9:29 universal time.Data collected from four sites on the path of the event were analyzed and occultation time at each site was calculated.Combining the time span with orbital speed of 313 Chaldaea,we calculated the length of the cross section of the asteroid.We used Occult 4 software to fit an ellipse to the data and derived the size and shape of the asteroid.We also estimated position errors in our measurements.The feasibility and advantages were discussed to mobilize amateur astronomers to observe asteroid occultation events and to obtain useful data with their own equipments. |
