The "ring of fire" solar eclipse is coming up Thursday (June 10) and here's when you can watch it.

Total solar eclipses — which are relatively rare — happen when the moon covers the entire sun; the moon's orbit is tilted with respect to the sun and doesn't always perfectly align.

A "ring of fire" or annular eclipse happens when the moon is near its farthest point from Earth during an eclipse, so the moon appears smaller than the sun in the sky and doesn't block the whole solar disk.

The first locations where you can see the partial phase of eclipse — where the moon takes a "bite" out of the sun — will happen at 4:12 a.m.

The annular eclipse will start being visible in those northerly regions fortunate enough to see it at 5:49 a.m.

The last glimpse of the annular eclipse will happen at 7:33 a.m.

If the moment of maximum eclipse happens before sunrise, the eclipse magnitude — the percent of the sun that is covered by the moon — is denoted with an asterisk (*). .
