Welcome to Solar Physics Section, Hiraiso/CRL Solar Physics section in the Hiraiso Solar Terrestrial Research Center of the Communications Research Laboratory studies the mechanism of various kinds of solar activities such as flares. The research and development for "Space Weather Forecast" is also important topic for us. Our current jobs are as follows.

• Research of solar active phenomena with optical telescopes
• Research and development of optical instruments for solar observation
• Observations of solar burst with radio telescopes
• Daily monitoring and forecast of solar activities as well as relating R & D.
• Construction of database.
