CAWSES-II Space Weather International Collaborative Research Database in Japan (2009-2013)

The on-line database contains the following items obtained at the National Astronomical Observatory of Japan during the CAWSES period, by means of optical observations.

Old data obtained at the Tokyo Astronomical Observatory, University of Tokyo, are also included. Image data are available in gif or jpeg format, and most of them are also provided as FITS-format digital data.
