Arcus, also known as a Shelf Cloud, is a long, dark, horizontal roll or shelf running along the base of the storm cloud’s front edge, so it is the first cloud feature to arrive as the storm approaches an area. This storm system was spotted over Danforth, Ontario, Canada.

22-degree halo is seen as the sunlight is refracted through the ice crystals of thin layers of high clouds, such as cirrostratus in this case. Note how it 'ceases to exist' where there are no thin layers of clouds present. This example was spotted over Lake Stevens, Washington, US.
