The Brightest Full Moon in 15 years
So perhaps the comment I made last night about "light pollution being at an all time high during the holidays because even the semi-rural suburbs were glowing in the distance" might have been... ugh this is painful... wrong? Oops. Yesterday, Wired's Clara Moskowitz wrote about the phenomenom:
"Because the moon orbits along an egg-shaped ellipse, not a circle, its distance from us changes. Today, the moon is approaching its nearest point to Earth, so it should look about 14 percent bigger and 30 percent brighter than this year's other full moons, according to NASA. Since the moon takes about 28 days to orbit Earth, it reaches its point of closest approach, called perigee, about once a month. But since the moon's orbit isn't a perfect oval — rather, it wobbles — some perigees are closer than others. Tomorrow's approach will be the closest the moon has come to Earth since 1993."
