Research Abstract

We have developed an automatic observation system with` Kanata' 1. 5-m high-speed moving telescope and an wide-field optical polarimeter HOWPol, and discussed the magnetic structure of GRB relativistic jets on the basis of the polarization of early afterglow detected by this system. We have also discussed the early observation for other outburst phenomena of stars like supernovae and classical novae.
