CCD photometric observations of 10 main-belt asteroids were obtained from the Center for Solar System Studies from 2019 January to March. In light of recent period analysis, images of 2120 Tyumenia obtained in 2004 were re-examined. The resulting analysis found a period of 17.515 h, which is consistent with the recent results.
2019年1月至3月期间，从太阳系研究中心获得了10颗主带小行星的电荷耦合器件（CCD）光度观测数据。鉴于最近的周期分析，对2004年获得的2120号小行星秋明的图像进行了重新检查。分析结果发现其周期为17.515小时，这与最近的结果一致。
