Sun halo

At 14:30 this afternoon there was a very nice example of a halo around the sun also known as a 22 degree sun halo.

The halo is formed by the suns rays passing through high altitude ice crystals and is usually a sign that it will rain within the next 24 hours.

When I see a distinctive cloud formation, I take photographs at regular intervals as the sky changes and note the resulting weather for future reference.
