• Photometric catalog for each date (csv):
  • Spectral irradiances for all the bands
  • AB magnitudes for Bands 2–3
• Photometric catalog after binning (csv):
  • Spectral irradiances for all the bands
  • AB magnitudes for Bands 2–3
• Figures of the light curves: black and blue dots represnt original and binned data points, respectively.
• Only the data after January 2017 can be used. (Before that, bias was large)
• See this page for more detail.
• The operation of Himawari-8 finished on December 13th, 2022, and Himawari-9 is in operation now. We are analyzing and checking the Himawari-9 data.
• The data before 2022/12/13 04:30 was taken by Himawari-8, and data after that was taken by Himawari-9. Currently, we haven't carefully validated the Himawari-9 data, so please be careful (Maybe there is a bias between Himawari-8/9 photometries).
