No matter where you are in North America on August 21, 2017 the new audio cues feature will guide you through the Great American Total Eclipse of 2017. Read on to learn what you will see and now hear during the solar eclipse. Warning : Using event timers and audio cues never implies it is safe to take off any type of eye protection at any time when observing the Sun. This app’s calculations are estimations and are not guaranteed. Please use caution, as it is never safe to view the Sun (eclipsed or otherwise) without proper and certified eye protection.

When that moment of totality (or annularity) occurs you get the opportunity to witness the simultaneous sunsets and sunrises on another planetary body. The unique geometry of our Earth-Moon system allows us to view this rare spectacle as the perceived lunar size is nearly the exactly the same as of the Sun:  There’s no other place in the solar system where this occurs. Solar Eclipse Diagram the orbit of the Moon is planar and the geometry of it’s shadow is conical, when cast on another rotating spherical body, the Earth, the lunar shadow is contorted into unique and odd shapes. During a solar eclipse, the shadow of the Moon is rarely circular, and is often an odd ellipsoid shape that races from 10,000 to 2000 mph across the surface of the Earth. NASA has provided excellent animations of the Moon’s traversal across the globe during eclips...
