You can read the table above as follows: On August 21, 2017 in Washington, District of Columbia (UTC -6), an eclipse of type partial solar eclipse will start at 13:17:52, the maximum eclipse will occur at 14:42:48 when the Sun reaches an altitud of 56° and azymuth of 223°;this event will come to an end at 16:01:38 and will have a magnitud of 0.845 (the magnitude of an eclipse is the ratio of the apparent size of the Moon to the apparent size of the Sun during an eclipse) and an obscurity of 0.81 (the fraction of the Sun obscured).

We must take into account the altitude of the sun, for example, in Honolulu, Hawaii, due to the low altitude of the Sun (5 degrees) this solar eclipse will not be very obvious.

your city is not listed?

To obtain eclipse information for a particular city, you may load the interactive world map. In addition, the world map shows the path of totality and the coordinates of the greatest eclipse. (Due to some limitations, this map may sometimes not load)

Protect your eyes

Observers must be very careful while viewing the solar eclipse. Our advice is to never look at the Sun with the naked eye.For safety, you must always use sunglasses, telescopes and binoculars with special filters. Never use these equipments without protection as the Sun's ultraviolet and infrared light may harm your eyes or cause blindness if you look at the Sun directly.
