MAPLE FALLS, Wash --Suzette Roberts snapped these photos neat Maple Falls Wednesday.

The photos show the bottom half of a corona.

A corona can form all the way around the sun when the sun’s rays are bent by water droplets high in the sky.

This one only shows the bottom half of a full corona – because the requisite water droplets are not present 'above' the sun.

A corona is different from a halo around the sun.  Halos are formed with the sun’s ray are bent by ice crystals.  You can tell the difference by the colors.  Halos have red on the inside; coronas have red on the outside.
