Research Abstract

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.
