Follow up observations of microlensing events were executed by world-wide observation network to find extrasolar planets. New planets (MOA-2007-BLG-192Lb, MOA-2008-BLG-310Lb、MOA-2009-BLG-319Lb) have been discovered. From the analysis of the distribution of planets, it is concluded that cold neptunes are common. As a by-product of microlensing observation, planet search with Transit Timing Variation method was done using B&C telescope. Then, a limit on the existence of second planets was imposed for WASP-5.

全球观测网络对微透镜现象进行了跟踪观测，以寻找太阳系外行星。新发现的行星（MOA-2007-BLG-192 Lb，MOA-2008-BLG-310 Lb，MOA-2009-BLG-319 Lb）。从行星的分布分析，得出冷海王星是常见的。作为微透镜观测的一个副产品，利用B&C望远镜进行了凌日变时法行星搜索。然后，对WASP-5的第二颗行星的存在施加了限制。
