Lunar Eclipses don't have a set pattern in which they come, because the conditions have to be absolute and no other condition can be present, thus they only happen several times a year. Lunar eclipses only happen at full moon and when the Moon is in Earth's plane of orbit around the sun.

The next eclipse that will be seen in Johns Creek, GA will be on April 15, 2014. This eclipse will be a total eclipse of the moon, lunar eclipse, and will be almost fully visable from North America.

During a Lunar Eclipse, the earth lies between the sun and the moon which results in the shape of the earth's shadow reflected upon the moon. The Earth is blocking the sun's rays on reaching the Moon, making the Moon an eclipse. The Moon can get a reddish color due to the fact that the sun's rays have to penetrate the Earth's atmosphere in order to get to the moon since it is in the middle. The white light that goes through the atmosphere gets filtered and the blue-colored light goes, leaving red light, which is reflected on the moon. = SUN EARTH MOON

As the earth spins on its axis, producing night and day, it also moves about the sun in an elliptical (elongated circle) orbit that requires about 365 1/4 days to complete. The earth's spin axis is tilted with respect to its orbital plane. This is what causes the seasons. When the earth's axis points towards the sun, it is summer for that hemisphere. When the earth's axis points away, winter can be expected. Since the tilt of the axis is 23 1/2 degrees, the North Pole never points directly at the Sun, but on the summer solstice it points as close as it can, and on the winter solstice as far as it can. Midway between these two times, in spring and autumn, the spin axis of the earth points 90 degrees away from the sun. This means that on this date, day and night have about the same length: 12 hours each, more or less.

For the Northern Hemisphere, the axis points most toward the sun in June (specifically around June 21), and away from the sun around December 21. This corresponds to the Winter and Summer Solstice (solstice is Latin for "the sun stands"). For the Southern Hemisphere, this is reversed.

For both hemispheres, the earth is 90 degrees away from the sun around March 21 and then again around September 21. This corresponds to the Fall and Spring Equinox (equinox is Latin for "equal night"). Everyplace in the world has about 12 hours of daylight and 12 hours of night.

The revolution of the Moon around the Earth makes the Moon appear as if it is changing shape in the sky. This is caused by the different angles from which we see the bright part of the Moon's surface. These are called "phases" of the Moon. Of course, the Moon doesn't generate any light itself; it just reflects the light of the Sun. The Moon passes through four major shapes during a cycle that repeats itself every 29.5 days. The phases always follow one another in the same order.
