The summer of 2018 continues to be a blockbuster for fantastic celestial events.
Following July's total lunar eclipse , some sky-watchers will be treated to a partial solar eclipse on August 11.

During a solar eclipse, the moon passes between the Earth and the sun, casting a shadow on our planet. If you're watching from Earth, the moon appears to cover the sun.

How much the moon covers the sun depends on your location on Earth. The coming partial solar eclipse will be most visible at the North Pole, EarthSky reports — there, the sun's diameter will be 65% covered. In the northern city of Yakutsk, Russia, the sun will be 57% obscured. In Greenland, the sun will be 50% covered.  http://earthsky.org/?p=283900

People in Seoul, South Korea, and Shanghai, China will be treated to the partial eclipse as well. The moon will obscure 35% and 20% of the sun in those cities, respectively.

Even though the sun gets fully or partially blocked during an eclipse, you need glasses with special filters to watch the event without damaging your eyes, since the light that surrounds the moon is still intensely bright.
