With the sky darkened, you may be able to see some stars and planets, depending on viewing conditions at your location. Bright Venus may appear to the Sun’s right or bottom-right, with dimmer Jupiter at the Sun’s left or upper-left.

Also, don’t forget the Moon! Just prior to totality, the last rays of sunlight will slip through lunar valleys on the Moon’s limb, creating a string of pearly dots known as Baily’s Beads. You can watch through a solar filter or eclipse glasses as the beads slowly wink out, until the last one shines bright, giving the impending eclipse the look of a diamond ring. The phenomenon will appear in reverse at the end of totality.
