Solar and solar wind: Optical and radio solar observation for space weather

Abstract

Researches on solar observation technique and data utilization are important issues of space weather forecasting program. Hiraiso Solar Observatory is a facility for R and D for solar observation and routine solar observation for CRL's space environment information service. High definition H alpha solar telescope is an optical telescope with very narrow pass-band filter for high resolution full-disk imaging and doppler mapping of upper atmosphere dynamics. Hiraiso RAdio-Spectrograph (HiRAS) provides information on coronal shock wave and particle acceleration in the soar atmosphere. These information are important for daily space weather forecasting and alert. In this article, high definition H alpha solar telescope and radio spectrograph system are briefly introduced.
