This week's partial eclipse is a prelude to the total solar eclipse, which will be visible in North America two weeks later (August 21). "You get lunar eclipses when you have full moons, and you have solar eclipses when you have new moons".
It is only when a part of the Moon passes through the umbra, a partial lunar eclipse is seen. To see the eclipse, spectators are advised to turn their backs to the setting sun and look towards the east-southeast horizon.
A solar eclipse, according to Space.com, can only happen when the moon is at one of two nodes of its orbit, or when the moon crosses the path of the sun.
This is where the Sun, Earth and Moon are aligned to form an exact or an nearly straight line.
"We're going to be looking at this event with unprecedented eyes", said Alex Young, a solar physicist who is coordinating NASA's education and public outreach. This results in Earth's shadow looking like it's about to "take a bite" out of the moon, instead of covering it completely. Other areas of the continental states will see a partial eclipse.
After the rains cleared up, people came out in large numbers all over the country to watch the moment when the moon, sun and the Earth became one as they aligned in nearly a straight line. Eclipse Begins - 10.52 pm; Maximum Phase of the Eclipse - 11.50 pm; Eclipse Ends - 12.50 am.Total Duration of the Eclipse Referring to Umbral and Penumbral Phases - 05h 1m.
When the partial lunar eclipse happens worldwide. A partial eclipse will be visible along the periphery. "Our astronomy club will have a couple of telescopes set up with the solar filter attached so you will be able to see magnified views of the sun that way". "When the moon passes through the faint shadow of the earth, penumbral eclipse takes place". We haven't had an eclipse do that in almost a century.
The North Shreveport Branch, West Shreveport Branch and Means Shreveport Branch will also be hosting watch parties during the eclipse.
On Monday, August 21, the roles of the moon and Earth will be reversed, as the moon casts a shadow across Earth.
