The moon will appear to take a "bite" out of the sun during a deep partial solar eclipse on Sept. 21.

Globally, September's partial solar eclipse will begin at 1:29 p.m. EDT (1729 GMT), with the maximum eclipse phase — when the moon covers the largest portion of the sun — occurring at 3:41 p.m. EDT (1941 GMT). However, exact timings vary by location. A detailed breakdown of eclipse times for different countries can be found in the table below. For a full breakdown, see Time and Date.

Only 16.6 million people, 0.2% of the world's population, live in areas where at least part of the solar eclipse will be visible, according to Time and Date. If you're not one of the lucky few in the path of the partial solar eclipse, you can watch all the action unfold live here on Space.com. Details to be released closer to the time.
