If you live within the viewing area, even
though most of the sun will be obscured by the moon, it’s essential to observe eye safety. This
includes using a proper solar filter or an indirect viewing method during ALL
phases of this eclipse.
An annular eclipse is the product of almost
the same celestial geometry as a total solar eclipse – that is, from the
perspective of some place on Earth, the moon crosses in front of the sun’s
But an annular eclipse is different in one important way – the moon is too far from Earth to obscure the sun completely, leaving the sun’s edges exposed and producing the “ring of fire” effect for which annular eclipses are known. Because the moon’s orbit is slightly oblong, its distance from Earth – and therefore its apparent size compared to the sun’s – is constantly changing.
Any time part, or all, of the sun’s surface
is exposed – whether during an annular eclipse, a partial eclipse, or just a
regular day – it’s essential to use
a proper solar filter or an indirect viewing method to view the sun. You
can NEVER look directly at the sun, and an annular eclipse is no

If you live in North America, you’ll have a
chance to see an eclipse later this year. On Aug. 21, 2017, a total solar
eclipse will cross the US – the first total solar eclipse in the contiguous US
in nearly 40 years! The path of totality for the August eclipse runs from coast
Within this narrow path of totality, the moon
will completely obscure the sun – unlike an annular eclipse – revealing the
sun’s outer atmosphere. People in other parts of North America will see a
partial solar eclipse, weather permitting. Find out what you can see during the
