Total Solar eclipse, 21AUG2017, Glendo, WY
seconds before the end of totality, the 101% apparent diameter Moon starts to move off and reveal the pinkish red photosphere of the Sun. The photosphere contains flares and prominences and is the last layer of the Sun before the coronal atmosphere. Normally, the brilliant chromosphere washes out any view of the photosphere and prevents us from viewing it, except in a Hydrogen Alpha telescope, or in this case the Moon blocking the chromosphere light. In a very few seconds after this exposure, the chromosphere shows again and hides the white corona and pinkish red photosphere until the next total eclipse in 2019.
