Twice a year the moon rises (roughly) at the eastern horizon; it happens at the full moon closest to each Equinox. With the Mall set up on a east-west axis, that means the moon visually align itself with the major monuments and buildings of the city. Because it rarely rises on that axis perfectly, the sight seems to always be different.
Phil, who has been taking these pictures for a number of years, came away with a great one this time. The first thing you notice is the orange coloring of the moon; that happens because the light the moon is reflecting is going through more of the Earth’s atmosphere than if it was at the apex of the sky. The atmosphere scatters the light and redshifts it (if you check out an earlier shot the redshift is more evident). But beyond the quirky rules of physics, the shot is well framed; with the Capitol dome fully visible, the size of the Washington Monument evident, and even the beautiful dome of the Natural History Museum. And then there’s the moon in the Reflecting Pool, which seals the shot. It’s certainly a gorgeous enough sight to keep one in love with DC!
