Best seen: moonrise on Tuesday, September 17 and Wednesday, September 18 An exceptional full moon to get outside and witness at moonrise and then again the next night as there will be two evenings to view it. The “Harvest Moon" will be the closest to the equinox and will move through the Earth’s outer shadow in space. On Wednesday, September 18 a partial lunar eclipse will result for the night side of Earth, including North and South America, Europe, Africa and the Middle East. It will also be the second—and second-biggest—“supermoon” full moon of the year. This is the full moon closest to the autumn equinox, and it traditionally provided extra light for farmers to harvest their crops.
