![]() ![]() The result is that full moon nights in the wintertime in mid-northern latitudes tend to be brightly lit add to that the odds that there is snow on the ground, and you get a night that is easier for people to see by.įull moons in December and January are also high enough that they can appear smaller – this is an illusion created by the fact that there is nothing near the horizon to give the moon scale. In the Northern Hemisphere the full moon tends to be lower in the sky in the late spring and summer months, while in the Southern Hemisphere, where it is winter, the moon is higher. One full moon phenomenon is that they are on the exact opposite side of the sky as the sun the position of the moon is the position the sun will be in six months later (or six months earlier). Moonrise times will differ by latitude because the Earth is tilted on its axis the Southern Hemisphere nights are longer, so the sun sets earlier and the moon rises earlier (from the point of view of people at that latitude). In Buenos Aires, the moon rises at 6:05 p.m. ![]() local time on May 5, according to the U.S. New York City observers will see moonrise at about on 8:13 p.m. the Moon sets at 4:48 a.m.įor those who won't see the eclipse, there is an ordinary full moon, in the constellation Libra. In Tokyo the eclipse starts just after midnight on May 6 at 12:14 a.m. ![]() Much further east the moon is in the western sky as the eclipse starts. The eclipse starts at 8:44 p.m., with maximum eclipse at 10:52 p.m. In New Delhi, one will see the eclipse start well after moonrise, which is at 6:45 p.m. Observers will see the rising moon touch the penumbra (which will be on the lower left) and see it get slightly darker over the course of about two hours. local time – the eclipse starts only a minute before that.

For example, in Paris, the moon rises at 9:16 p.m. To see the full effect of the penumbral eclipse properly one must be far east enough that the moon hasn't exited the penumbral shadow by moonrise. How high in the sky the moon is when the eclipse starts depends on one's location. If you were standing on the moon you would see the Earth block part of the sun's light, but not all of it – you'd have a partial solar eclipse. This means the slight darkening is more noticeable. This eclipse will have a much rarer condition, in which the entire moon will pass into the penumbra, but not the umbra. In the latter case, the darkening of the moon is difficult to see the penumbral shadow only "tints" the moon slightly and if the whole moon isn't covered by the penumbra that slight dimming is overwhelmed by the brightness of the lunar surface. Most of the time the moon either passes through the Earth's darker umbral shadow, creating a partial or total lunar eclipse, or only part of the moon passes through the penumbra. The inner part, where the Earth blocks all of the light from the sun to the moon, is called the umbra. Unlike a more typical partial or total lunar eclipse, in a penumbral eclipse the moon passes through the outer part of the Earth's shadow, called the penumbra. ![]()
