Here's how southern Denton County will experience the solar eclipse

This happens when the New Moon moves between the Sun and Earth.

If you've been anywhere near the Internet lately, you've most likely heard some gossip about the upcoming lunar eclipse. Because of this, only part of the moon's visible surface moves into the earth's shadow. In contrast, the inner or umbral shadow is a region where the Earth blocks all direct sunlight from reaching the Moon.

An annular eclipse occurs where the Moon appears to be smaller than the Sun, and its shadow could not fully cover the edges of the Sun, forming a "ring of fire".

These events are of only academic interest because they are subtle and hard to observe. If you're having a hard time visualizing this, NASA created a video to illustrate the way the moon orbits Earth.

Even a few clouds could put a damper on the event that lasts just a mere 2 minutes and 40 seconds. Because the sun will not be completely blocked, you must use "eclipse glasses" or other devices specifically made for solar viewing in order to safely view the partial eclipse, or risk permanent loss of vision.

You need the right protective glasses, such as those manufactured by Rainbow Symphony, American Paper Optics, Thousand Oaks Optical or TSE 17.

Lunar eclipses also have the advantage of being visible from the entire hemisphere of the Earth where the Moon is above the horizon, rather than being most impressive along a narrow track.

Unlike solar eclipses, no special equipment is required to view a lunar eclipse, although a pair of binoculars or a telescope may enhance the view of the event.

"Every total solar eclipse brings with it a lunar eclipse either two weeks before or after", Slooh astronomer Paul Cox said in a statement.

The total phase would end at 01:02 PST (on August, 21st) whereas the Penumbral Eclipse would end on 02:04PST (on August 21st).

This moon has been called the "Sturgeon Moon" by First Nations tribes in reference to the species of large fish that's easy to catch in the Great Lakes and Lake Champlain around this time of year.
