FEATURES On Friday, Nov. 19, the Sun, Earth, and the Moon (in that order) will line up and most of Moon will trek through Earth's umbra, the darkest part of its shadow. Greatest eclipse, at which point the Moon is as deep in Earth's umbra as it will get, occurs at 4:02:56 a.m. EST. A good estimate of the Moon's brightness at mid-eclipse is about magnitude -5; it will be brighter than Venus (-4.7), but only 0.1 percent the brightness of the Full Moon.
