Don't mistake about the lattitude of Brittany ! The vertical path of the sun is just the result of picture registration. In fact the sun is moving down to the right.

Crepuscular rays observed as the sun was setting
down over Mount Aigoual (Cévennes mountains).
Captured with CANON EOS300D and 18mm lens.

Sun setting behind trees.
Spectral sun light spreading gives a green color to the top of
the solar limb. This phenomenon is commonly called green ray.
With naked eye, it is perceived just a few seconds before the sun
is fully set under the horizon.

Solar halo captured at the bottom
of a building.
This circular halo whose radius is 22°, is the result of the
decomposition of sunlight by ice cristals in cirrus clouds.

Circumzenithal arc
A circumzenithal arc is produced by refraction of sun light by
ice cristals in high clouds. Appearing very closed to zenith, it’s
often remains ignored. It’s always surprising to see this
inversed rainbow rolled up around zenith. A circumzenithal arc is
frequently associated with a 22° halo.

This iridescence is called sundog.
Sundogs appear symetrically 22° apart from the sun, at the same
level as the sun. This one was captured on the right side of the
sun.

Evolution of a
parhelion (900x600 DIVX compression 1954k)
This accelerated movie represents a real duration of about 40 minutes (5 seconds between consecutives exposures with CANON EOS300D and Pocket Shutter sequencer).

Sometime clouds are covered with
magnificent nacreous colours. Such clouds are called iridescent
clouds. This phenomenon occurs when the size of droplets
composing the cloud is uniform. Iridescence results from
interferences between sun rays diffracted by droplets.

forest in Quebec. This phenomenon is the result of the sun light
reflecting on atmospheric ice particles.
