Greetings all,
As I write, there is a lovely optical display in the skies over
Red Deer,
Alberta, Canada (latitude: 52°). This is the best I have seen in the last
several years. The temperature has taken a fairly sudden drop in the last
day, currently -20°C. The sky is clear, but ice crystals are forming and
falling slowly from the sky.
Currently visible are:
22° halo: complete
46° halo: complete
22° parhelia (sun dogs): very bright and coloured
upper arcs to BOTH halos: (Parry or tangent?)
sun pillar
circum-horizontal arc: partial, about 50° each side of sun.
