Night sky guide for February 2017

February 11 - Penumbral lunar eclipse - 00:45 UTC. Like other lunar eclipses, penumbral eclipses occur whenever the Earth passes between the Moon and Sun,
such that it obscures the Sun's light and casts a shadow onto the Moon's surface. But unlike other kinds of eclipses, they are extremely subtle events to
observe. In a penumbral eclipse, the Moon passes through an outer region of the Earth's shadow called the penumbra. This is the outer part of the Earth's
shadow, in which the Earth appears to cover part of the Sun's disk, but not all of it. As a result, the Moon's brightness will begin to dim, as it is less
strongly illuminated by the Sun, but the whole of the Sun's disk will remain illuminated to some degree. Although the Moon's light dims considerably during
a penumbral eclipse, this is only perceptible to those with very astute vision, or in carefully controlled photographs. The eclipse will be visible
throughout most of eastern South America, eastern Canada, the Atlantic Ocean, Europe, Africa, and western Asia.
