The eclipse promises to gain extra publicity because it coincidentally lines up with two other lunar events. The January 31 Full Moon is the second of the month, so it also will be touted as a “Blue Moon.” And it so happens that this is 2018’s second-closest Full Moon, and thus the year’s second largest, which no doubt will compel some people to label it a “Super Moon.”
From North America, the eclipse occurs before dawn and delivers better views to those who live farther west. The eclipse action starts when the Moon first touches the lighter, outer part of Earth’s shadow, called the penumbra, at 5:51 a.m. EST (2:51 a.m. PST). [See the table below for eclipse times in all time zones.] Unfortunately, the penumbra imparts only a subtle darkening to the lunar surface, and few observers will notice more than a dusky shading on the Moon’s western half.
