Unusual Volcanic Sunsets

As expected, reports are filtering in of spectacular sunsets from the Sarychev volcanic eruption earlier in June. This picture is from Canada: keep an eye on the sky for potential over your back yard too!

The volcanic cloud reached upwards of 65,000 feet, penetrating well into the lower stratosphere. Here, the sulfur dioxide gas combines with water vapor to form a weak sulfuric acid solution. These droplets remain aloft for up to three years, producing a slight haze which reflects and refracts sunlight into amazing color schemes.
