Eclipse on Cue

New Eclipse Explorer Audio Cues: What you’ll see (and hear) during the eclipse! 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. To demonstrate all audio cues, you may “time travel” by long-pressing an eclipse circumstance such as “Partial Eclipse Begins” or “Total Eclipse Begins”. Long press circumstances for time travel mode and audio cue demo. Audio cues may be turned on or off in the app drawer menu on the left. Turning on the audio cues will play

The New Eclipse Explorer App

After a long and nearly complete code rewrite, the Eclipse Explorer Mobile App: Version 3.0 is now available:  Just in time for the Great American Solar Eclipse of 2017!  Read on for further information. App screen shot. What is Eclipse Explorer? Eclipse Explorer is a free astronomical app that allows you to view the circumstances for solar eclipses that occur between 1900 and 2100 using your GPS defined location.  It uniquely features countdown timers to eclipse events at your specific location, simulates the position of the Sun and Moon, and draws the location of the Moon's shadow on the Earth in real-time.  Lookup solar eclipse circumstance data from around the world: Touch your desired location or lookup by city/point of interest/address. Why Create Eclipse Explorer? There are numerous online sources for eclipse circumstances, however, very few are mobile friendly and easily integrate with a mobile device which often offers very accurate time and location to the user: A

Coding Eccentricities

Standing in the Shadow of the Moon Solar eclipses offer the unique ability to stand in the shadow of a massive solar system body. 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 eclipses.
