The low, partially eclipsed moon in deep blue twilight should offer a wide variety of interesting scenic possibilities for both artists and astrophotographers. and Canada, the moon will already be partially immersed in the umbra. It's almost as if a dimmer switch were slowly being turned down on the surrounding landscape and deep shadows of a brilliant moonlit night were beginning to fade away.Īcross the western U.S. Also notice that the edge of Earth's shadow projected on the moon is curved - visible evidence that Earth is a sphere (or, more precisely, an oblate spheroid), as deduced by Aristotle from lunar eclipses he observed in the fourth century B.C. But much later, as it moves in deeper, you'll probably notice the moon glowing dimly orange, red or brown. At first, the moon's limb may seem to vanish completely inside the umbra. As the minutes pass, the dark shadow appears to slowly creep across the moon's face. The umbra is much darker than the penumbra and fairly sharp-edged. The partial phases of the eclipse begin the pace quickens, and the change is dramatic. A small, dark scallop begins to appear on the moon's upper-left (northeastern) limb. The moon now begins to cross into Earth's dark central shadow, called the umbra. Just before the moon begins to enter Earth's dark umbral shadow, the penumbra should appear as an obvious smudge or tarnishing of the moon's upper left portion. This will become increasingly evident as the minutes pass, with the shading appearing to spread and deepen. Start looking for a very subtle light shading to appear on the moon's upper left portion. Now, the moon has progressed far enough into the penumbra that it should be evident on the moon's disk.

For about the next 40 minutes, the full moon will continue to appear to shine normally, but with each passing minute, it is progressing ever deeper into Earth's outer shadow. Earth's penumbral shadow is so faint that it remains invisible until the moon is deeply immersed in it, when the penumbra has reached roughly 70% across the moon's disk. Although the eclipse begins officially at this moment, you won't see anything unusual happening to the moon yet. The penumbra is the pale outer portion of Earth's shadow. The shadow cone of the Earth has two parts: a dark, inner umbra , surrounded by a lighter penumbra. Here's a breakdown of the stages of the total lunar eclipse and what you might see during each one: 1) The moon enters the penumbral shadow Phases of the Blood Moon total eclipse by time zone Stage When dashes are provided, it means that the moon has not yet risen above the horizon. 8, except when in italics, which corresponds to p.m. In the timetable below, local circumstances are provided for seven different time zones. In November it was time to set beaver traps before the swamps freeze to ensure a supply of warm winter furs. The November full moon is traditionally known as the Beaver Full Moon.The native Americans of what are now the northern and eastern United States kept track of the seasons by distinctive names given to each recurring full moon, these names being applied to the entire month in which it occurred.
