Moon over Lower East Side
Tuesday, June 17th, 2008The full Moon of June 18th is a “solstice moon”, coming only two days before the beginning of northern summer. This week’s high solstice sun gives us a low, horizon-hugging Moon and a strong Moon Illusion. Low-hanging moons look unnaturally big. At first, astronomers thought the atmosphere must be magnifying the Moon near the horizon, but cameras showed that is not the case. Moons on film are the same size regardless of elevation: example. Apparently, only human beings see giant moons.
The above is according to NASA. To my human eyes tonight’s moon, the night before full, was not that impressive, but it might have been more so if I’d been in a position to see it really low on the horizon.
