Short summary
The DSCOVR/EPIC instrument located near the Lagrange 1 Earth–Sun gravitational balance point is able to view the entire sunlit disk of the Earth. This means that during the eclipse of 21 August 2017 EPIC was able to see the region of totality and the much larger region of partial eclipse. Because of this, EPIC is able to measure the global reduction of reflected solar flux. For the wavelength range 388 to 780 nm, we estimated a 10 % reduction in reflected radiation.
