In this scenario, the earth blocks some of the sun's light from directly reaching the moon's surface and covers all or part of the moon with the outer part of its shadow, also known as the penumbra.
The August 7 lunar eclipse is associated with the upcoming major August 21 solar eclipse. Lunar eclipses occur when the moon passes through some portion of the Earth's shadow. It has been dubbed the Great American Eclipse as it will be visible to most people in North America for the first time in 38 years.
The path of totality for the solar eclipse will stretch from OR to SC.
According to Masoud Atiqi, director of Iran Amateur Astronomy Society, all the lunar eclipses since the total eclipse in September 28, 2015, have been partial or invisible to human eye.
"On February 11 this year there was a penumbral eclipse of the moon". It will also be visible from all parts of the Indian sub-continent, Duari said. To observe the eclipse safely, all one needs is a solar filter that will protect the eyes against the concentrated radiation coming off the Sun when viewing with naked eyes/binoculars/telescope.
To find out whether you'll need to drive to the eclipse or just step outside your house, use this interactive map that shows whether you are in the path.
Do not look at the uneclipsed or partially eclipsed Sun through an unfiltered camera, telescope, binoculars, or other optical devices.
