Because of the eruption of Kasatochi, an Alaskan volcano, observers in the Northern Hemisphere have been witnessing some great sunrises and sunsets. The eruption occurred on 07 August 2008, and it sent ash and sulfur dioxide into the stratosphere, where the winds have carried it across North America and parts of Europe.
The photo to the left was taken on 30 August 2008 from Kansas, USA.
The particles have caused scattering of light, which gives it more vibrant colors at the red end of the spectrum. Hence, brighter and more colorful beginnings and endings of our days (or nights, if you will).
