The Four Eclipses in 2017īelow are brief descriptions of this eclipses in 2017 of the Sun and Moon. But an annular's path is likewise narrow, and outside of it observers see only a partial cover-up. This circumstance is known as an annular eclipse, so-called because you can see a ring, or annulus, of sunlight surrounding the lunar disk. Occasionally the Moon passes directly in front of the Sun but doesn't completely cover it. Outside of that path, about half of the daylit hemisphere of Earth is able to watch a partial eclipse as the Moon obscures a portion of the Sun. Eclipses of the Sun or Moon can only occur when the Moon crosses the plane of Earth's orbit (orange circle) very close to the time of new or full Moon.Ī completely eclipsed Sun can be viewed only from a narrow track or path on Earth's surface that's typically just 100 miles (160 km) wide. In November 2013, for example, planeloads of eclipse-chasers converged in a remote portion of northern Kenya to watch just 11 seconds of totality. With its brilliant disk completely covered, the Sun's ghostly white outer atmosphere is momentarily revealed for durations from seconds to several minutes. If the Moon completely hides the Sun, the eclipse is considered total. However, solar eclipses more tightly restrict where you can see them because the Moon casts a smaller shadow than Earth does. (But there's still an element of luck involved - after all, the sky has to be clear!) Both of these geometries will be in play during 2017's two lunar eclipses.įortunately, every lunar eclipse is observable anywhere on Earth where the Moon is above the horizon. And if its disk passes just outside the umbra, it still encounters the weak penumbral shadow cast by Earth. If the Moon skims part way into the umbra, only the partial phases occur. A long-exposure image captured red hues on the portion of the Moon inside the umbra during the lunar eclipse on October 8, 2014. That was the case during the widely viewed event in September 2015, which marked the conclusion of a series of four consecutive total lunar eclipses in 2014–15! Such eclipse tetrads are not common - the last one occurred during 2003–04, but the next won't begin until 2032. If it goes all the way in, we see a total lunar eclipse that's preceded and followed by partial phases. Three types of lunar eclipse are possible ( total, partial, and penumbral) depending on how deeply the full Moon plunges into or near the umbra, our planet's dark, central shadow. ![]() (The technical name for that, by the way, is syzygy.) These alignments don't happen at every new and full Moon because the lunar orbit is tipped about 5° to Earth's orbital plane - only occasionally do the Sun, Earth, and Moon line up exactly enough for an eclipse to occur. Conversely, a lunar eclipse takes place during full Moon, when our satellite passes through Earth's shadow. Why Do Eclipses Happen? Here's the glorious solar corona, as recorded by Fred Espenak during the total solar eclipse on August 1, 2008.Ī solar eclipse, such as the one pictured at right, occurs only at new Moon, when the lunar disk passes directly between us and the Sun. But both of 2017's solar eclipses are "central" events: one annular and one total. Neither of the lunar eclipses is total (though we'll have two of those in 2018). The fewest possible is four, as will be the case in for eclipses in 2017. Up to seven of them can take place in one year, though the last time that happened was 1982. on August 21st.Īny list of nature's grandest spectacles would certainly include eclipses of the Sun and Moon. But the solar offerings are much better, with an annular observable from the Southern Hemisphere on February 26th and the Big One - a total solar eclipse crosses the continental U.S. This section sets out all the major Pokémon GO events unrelated to real life events as well as their bonuses and special features.The eclipses in 2017 don't include great lunar eclipses, with a deep penumbral event on February 11th and a partial on August 7th. These range from giving special Pokémon, to extra bonuses and even special Raid Bosses. Like most games, Pokémon GO runs various special events and in these events, many of the mechanics and systems alter sightly in order to provide a different themed experience.
