Fast changing weather conditions also trigger optical phenomena as the sun interacts with ice chrystals in the atmosphere (high clouds).
In this section I show my most recent picures from most common halo's, sundogs and rainbow.
On august 3, 2015 I could make the the picture below. After modification using CS4 the picture shows different phenomena. From top to bottom :
Circumzenital Arc
"attached" Supralateral Arc
Pary Arc and Tangent Arc
22° Halo Arc
On the right/low end a sundog
