Partial Solar Eclipses

๐ŸŒž ๐ŸŒ‘ ๐ŸŒŽ

When the Sun is completely blocked out we called it a total solar eclipse, and often this is what people think of with an eclipse. But a partial eclipse can be just as exciting.

Partial Lunar Eclipse

The moon appears to block partโ€”but not allโ€”of the sunโ€™s disk (photosphere).

The Sun, Moon and Earth are not in a straight line. It appears as if the Moon took a bite out of the Sun.

This composite image of seven pictures shows the progression of a partial solar eclipse near from Ross Lake, Northern Cascades National Park, Washington on Monday, Aug. 21, 2017. The second to the last frame shows the International Space Station, with a crew of six onboard, in silhouette as it transits the Sun at roughly five miles per second. A total solar eclipse swept across a narrow portion of the contiguous United States from Lincoln Beach, Oregon to Charleston, South Carolina. A partial solar eclipse was visible across the entire North American continent along with parts of South America, Africa, and Europe.

๐ŸŒž What is a Partial Solar Eclipse? ๐ŸŒ‘

A partial solar eclipse happens when the Moon passes in front of the Sun, but only partially covers itโ€”leaving a crescent of the Sun shining through! ๐ŸŒž๐ŸŒ‘

Itโ€™s like the Moon is taking a bite out of the Sun ๐Ÿช, but not enough to fully block it! The result? A super cool sky show where the Sun looks like a crescent or a “cookie bite.” ๐Ÿชโœจ

Unlike a total solar eclipse, where the Moon completely covers the Sun, in a partial eclipse, the Sun is only partially obscured. How much of the Sun gets covered depends on your location. Some places might see just a sliver of the Sun hidden by the Moon, while others get a larger chunk covered. ๐Ÿ•๐Ÿ”ญ

It’s a cosmic event you wonโ€™t want to miss! But rememberโ€”never look directly at the Sun without protection, or you might end up with a bad case of “eclipse eye!” ๐Ÿ‘€๐Ÿšซ

Get ready for the celestial magic! ๐ŸŒŒ๐ŸŒž

PROTECT YOUR EYES!

Unlike a total solar eclipse, at no time will this be safe to view with the naked eyes. Be sure to carefully read the details to understand how to protect your eyes! Homemade filters or ordinary sunglasses, even very dark ones, are not safe for looking at the uneclipsed or partially eclipsed Sun.

The Experience

If you’re not in the direct path for a total or annular eclipseโ€”but still within the outside of the pathโ€”this is what you may have seen with proper eye protection.
