Scenes from patrol bracketing last week………. For those of you who have been away from us the recent cold snap produced skies with the most spectacular hues, blooming with pinks, reds and oranges. First, a lesson in the colors of the rainbow: Blue light has a short wavelength, so it gets scattered easiest by air molecules, such as nitrogen and oxygen. Longer wavelength lights -- reds and oranges -- are not scattered as much by air molecules. During sunrise and sunset, light from the sun must pass through much more of our atmosphere before reaching our eyes, so it comes into contact with even more molecules in the air. Much of the blue light gets scattered away, making the reds and oranges more pronounced. Apparently our most recent weather patterns allow for dry, clean Canadian air to sweep across the country, and more colors of the spectrum make it through to our eyes without getting scattered by particles in the air, producing brilliant sunsets and sunrises that can look red, orange, yellow or even pink Sun Rise Monday January 05, 2015, facing East over Pilgrim Lake from the Truro/Provincetown town line. Sunset Friday January 09, 2015 extending West over Hatches Harbor from the runway approach end at Provincetown Municipal Airport.
