Just flare that's caused by UV, which can occur when
you've got a lot of blue sky in the frame.
Skylight contains enough UV to cause lens flare even
when shooting away from the sun. It's not enough
to make the pictures look completely washed-out,
but it does reduce contrast.
Since UV filters don't effect visible light, they don't
affect flare caused by a visible light source in the
frame.
UV filters also have no effect on a multi-coated lens,
because multi-coated lenses are virtually opaque to
UV light already.
