Abstract | A video of darkening scenery during the 15 min prior to totality of the 21 August 2017 total solar eclipse is presented and discussed. The luminances of the scenes at 1 min intervals are obtained by averaging pixel data of stills from the video. The experimental results are compared to the theoretical model of uniform radiance from the exposed area of the Sun during the eclipse. The measured values deviate from the model since light from the solar disk decreases towards the edges of the Sun. (As Provided). |
