Time Lapse of 2017 Total Solar Eclipse

The link below is a time lapse of the solar eclipse from mid-Missouri. The hazy clouds added some color to the ring around the moon which is not visible in this sequence. Note the moon’s shadow, the “sunset” in all directions, and the “shrinking” of the sun at totality due to the reduced scattering of sunlight in the cloud.
