Study of the possible origin of radio transients by high accurate radio observation

尽管那须天文台与日本VLBI网络（JVN）之间的瞬变现象监测框架的准备工作比原计划推迟，但那须天文台的自动数据处理和探测信号评估系统的开发工作进展超过了预期。利用JVN高灵敏度VLBI系统对约900个射电源进行了瞬发观测。此外，我们成功地进行了快速跟踪观测的瞬变耀斑现象的活动星系核在2010年使用JVN。

Development of the automatic data reduction and detected signal evaluation system in Nasu observatory are progressed more than the one was expected, although preparing the framework of monitor of transient phenomena between Nasu observatory and the Japanese VLBI network (JVN) was more delayedthan originally scheduled. Snap-shot observations for about 900 radio sources with high sensitivity VLBI system in using JVN were carried out to start-up these system. Also, we succeeded to conduct a quick follow-up observation for the transient flare phenomenon from an active galactic nucleus in 2010 using JVN.
