Once in a Lifetime Halo Display Over Keene, Ontario
November 07, 2019
...
The clouds that drifted in this particular afternoon had just the right amount and configuration of ice crystals to produce a sky show very few people experience at my latitude in Keene, Ontario (Canada) -- a collection of ice halos and arcs rarely seen altogether. All this was clearly visible to the naked eye and the images I captured only hint at their true beauty. The following (top photo) is a list of what was visible during about a 30 minute period (bottom to top):
1) Parhelion (Sundog)
2) Parhelic Circle
3) 22 Degree Halo (Solar Halo)
4) Upper Tangent Arc
5) Upper Suncave Parry Arc
6) Supralateral Arc and
7) Circumzenithal Arc (CZA).
All but two of these arcs were quite evident. I've included a labeled version of the same photo (click on top photo), which will assist in figuring out what I’m referring to.
