Eclipse Explorer is a free mobile 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. A solar eclipse is one of nature's most amazing spectacles, however, clouds can ruin your day. Use this app to overlay satellite and radar data on the day of the eclipse to make sure you stay within the path of totality and away from the clouds!
