What is totality in a total solar eclipse?

Answer 1

Begins in the North Atlantic 186 miles south of Nova Scotia and quickly traverses the ocean. Southern England enjoys first landfall in Cornwall and parts of Devon. The path then crosses the English Channel and swings through northern France. Passing 12.5 miles north of Paris, the City of Lights will be darkened by an eclipse of magnitude 0.994.

Answer 2

It is when the umbra reaches the surface of the earth. The eclipse will appear to be 'total' only where the umbra passes during the course of the eclipse. The umbra is the shadow cast onto the earth by the moon, wherever the moon covers the face of the sun completely. In other locations where the moon covers only a part of the sun's face, it is the moon's penumbra that passes. Enjoy the eclipse safely. They are amazingly beautiful.

Answer 3

Totality is the brief period during a total solar eclipse when the moon completely covers the sun, creating a moment of darkness during the day. This is the only time when it is safe to view the sun without eye protection. Totality usually lasts for just a few minutes, depending on the specific location where the eclipse is being viewed.

Answer 4

That's a shadow, when the Sun's light is completely blocked by the Moon. This lasts for, at most, about 7 minutes.

Answer 5

A total or partial eclipse of the sun, also known as a solar eclipse, is caused by the moon passing across the face of the sun, so casting a shadow on the earth.
