H-α Solar Images
Last updated on Dec 4, 2020


  This section shows you the solar images taken with the CORONADO 40mm Hα solar telescope since Apr 2007. We can observe continuously various interesting phenomena in solar chromosphere like Plages (active regions), Flares, Dark filaments, and Prominences at the rim, and so on.
  Those images are rather observed data than works for appreciation, I've excluded detailed description in individual images.
