Preliminary Eclipse Images

Two images of the solar corona in polarized light on August 21, 2017. At left is an image taken during eclipse totality using a PolarCam camera (4D Technology). At right is an image in the same type of polarized light from the Mauna Loa Solar Observatory (MLSO) K-Cor coronagraph camera. Polarized light provides information on the density and magnetic field of the Sun's corona. The K-Cor instrument creates artificial eclipse images of the corona for daily observations of the corona.
