To paraphrase the NASA video below, think of the reddish hue of the eclipsed moon as the light of every sunrise and sunset occurring on Earth at that moment - the little bits of the sun's glow that are seeping around the edge of Earth's obstructive disc and making their way to the moon. This happens because our planet doesn't exactly block all the sun's light from reaching the moon and being reflected back to us. (It'll also be visible from South America.) An hour later, the moon should be fully in the umbral shadow of Earth, which projects a reddish glow on to our lone satellite. The eclipse will begin Monday night at 11 p.m. EarthMoonEarth communication (EME), also known as Moon bounce, is a radio communications technique that relies on the propagation of radio waves from an Earth-based transmitter directed via reflection from the surface of the Moon back to an Earth-based receiver. In the past, though, we've gone as long as three centuries with no tetrads, so it's a good time to be an eclipse fan. This will be one of just nine tetrads to occur in the 21st century. This grouping is called a tetrad, and it's a particularly rare tetrad because there's a good chance that all four events will be visible from most locations in the United States, according to NASA. The following table shows 10 locations with Sun near zenith position in the sky.This week's full-blown eclipse is just one of four we'll see in the coming months - the night will also appear to swallow the moon on October 8 of this year and April 4 and September 28 of 2015. The table below shows position of the the Moon compared to the time and date above: Time The ground speed is currently 435,24 meters/second, 1566,9 kilometres/hour, 973,6 miles/hour or 846,0 nautical miles/hour (knots). 23:26:00 UTC the Moon is at its zenith at Latitude: The table below shows position of the the Sun compared to the time and date above: Time The ground speed is currently 448,95 meters/second, 1616,2 kilometres/hour, 1004,3 miles/hour or 872,7 nautical miles/hour (knots). 23:26:00 UTC the Sun is at its zenith at Latitude: Business Date to Date (exclude holidays).
