LIVE Techno – Eclipse observers across the United States last weekend had the opportunity to witness the position of the Moon aligning with the Sun and creating an annular eclipse.

They watched from below for a brief experience that wasn’t too dark. NASA’s Space Climate Observatory (DSCOVR) captured the action from Earth orbit to get a different view of the event.
This solar eclipse is different from most solar eclipses which attract people’s attention when they occur. Because of its circular shape, it does not produce the awe-inspiring darkness that most people associate with this event.

Annular eclipses depend on a very unique set of circumstances. First, the Moon must be aligned with the Sun, as in a total solar eclipse.
In one of the photos, the Moon appears to completely cover the Sun due to its exact distance from the Earth. In total, people can only observe corona and the important things that happened at that time.

However, there is a slight difference between a total solar eclipse and what everyone saw in the most recent event. During an annular eclipse, the Moon is at its maximum distance from Earth.
The technical term for this distance is ‘apogee’. Because of this distance, the Moon does not ‘cover’ the Sun completely. The outer part of the Sun is still visible, which to observers looks like a reddish-orange ‘ring of fire’.
What NASA’s DSCOVR Mission Saw

As interesting as the view from Earth during an eclipse is, it is also interesting to see what happens from space. Quoted from Sciencealert, NASA’s DSCOVR mission took this image of the shadow as it crossed the United States.
It is placed at Lagrange Point 1, a gravitationally stable orbital point. The mission’s Earth Polychromatic Imaging Camera (EPIC) captured the scene. Typically, this camera is used to capture global views of planet Earth.
The view shows a sizable shadow visible along a wide band from Oregon in the Pacific Northwest to Texas in the South.
The darkest part of the shadow (the midline) is where one sees the golden ring surrounding the Moon. Observers outside the center line only see a partial eclipse. The duration of the eclipse (and the duration of the darkening) depends on the observer’s location.
More Eclipses
The eclipse frenzy continues this year and next with a lunar eclipse on October 28, which will be visible across Europe, Asia, Africa and Australia.
The next major solar eclipse will occur on April 8 and will be visible from Mexico to the United States to northeastern Canada. This will give satellites another opportunity to observe the shadow sweeping over the Earth when the Sun and Moon ‘meet’ again.
