Sun halo seen over Southwest Florida - WBBH News for Fort Myers,
Cape Coral & Naples, Florida  Sun halo seen over SWFL  Posted:
Updated:  You may have noticed a pretty neat phenomenon in our
Southwest Florida sky this afternoon.  Sky conditions were just
right to produce a colorful ring, or halo, around the sun.  This
optical effect is actually produced by sheets of really thin
clouds called cirrostratus.  What's neat about these types of
clouds is they're so high in the atmosphere that they're made of
ice crystals. It's the ice crystals that refract, reflect and
bend the light in such a way so that it produces the halo effect
around the sun.  On days when you see the sun halo, you'll also
notice that the sky has a faint white and hazy tint, which is
the thin veil of cirrostratus clouds.  It's also not uncommon to
see the same halo around the moon if the right type of cloud is
in place.  Notice the satellite image on the right side of the
page. This type of satellite uses infrared sensors to detect
clouds. Wh
