		Display at Whistler - Blackcomb Mountain, BC, Canada on 16th January 2002. Parry arcs oft reveal themselves during spectacular displays when the skies are dense with ice crystals. Only a small proportion need have the Parry orientation to produce an arc. Here it is characteristically sharp and relatively faint above the much brighter upper tangent arc. The solar elevation was 20°. Lynn Fink captured these images while skiing. The left hand sundog is also shown here. Images ©Lynn Fink reproduced with permission.
