What Is Alpenglow?

SEATTLE - Have you ever glanced at the mountains around sunrise or sunset, and seen a gorgeous pinkish or reddish hue on their summits? That's known as "Alpenglow."

As to what makes the gorgeous reds and pink synonymous with sunsets, you see sunlight as white, but it's made up as a combination of the colors of the spectrum.

Particles in the air will tend to scatter away the blue and green light part of the sunlight's spectrum, leaving behind the more-difficult-to-scatter red and orange colors. That's because red and orange lights has a longer wavelength than the blue and greens, making it less affected by particles.

So next time you're up skiing at sunset, be on the lookout for Alpenglow. We also have a few examples on the komotv.com Weather Web site under "Viewer Photos."

Chased the sun most of the day but there were enough breaks in the clouds to capture the solar eclipse and the massive
sunspot AR2192. You could view the eclipse through the clouds. These images were taken with a Meade AR6 refractor,
a Nikon D3000 DSLR, a Thousand Oaks Glass (type2) solar filter.

My husband works at Vigor on Harbor Island. This double rainbow was directly over downtown Seattle, but these buildings were in the way. Still makes a pretty cool picture.
