Lunar eclipse 2019 chicago4/4/2023 If the Moon skims part way into the umbra, as shown at right, only the partial phases occur - you'll see part of the Moon in nearly full sunlight, and part of it steeped in the deep, red-tinged umbral shadow.Īnd if its disk passes just outside the umbra, it still encounters the weak penumbral shadow cast by Earth. 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. A long-exposure image captured red hues on the portion of the Moon inside the umbra during the lunar eclipse on October 8, 2014. 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. In 2019, for example, two eclipses occur in January, two in July, and one in late December. (The technical name for that, by the way, is syzygy.) And, as the diagram above implies, those alignments occur roughly six months apart. 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. Eclipse "windows" occur six months apart.Ī solar eclipse, such as the one in August 2017, occurs only at new Moon, when the lunar disk passes directly between us and the Sun and the Moon's shadow falls somewhere on Earth's surface.Ĭonversely, a lunar eclipse takes place during full Moon, when our satellite passes through Earth's shadow. Why Do Eclipses Happen? 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. The mix of five events occurring in 2019 is especially interesting, because no two will be alike! There'll be three different types of solar eclipse - one each of partial, annular, and total - along with a total and a partial lunar eclipse. Up to seven eclipses of the Sun and Moon can take place in one year, though the last time that happened was 1982, and the fewest possible is four. The raw data is based on population estimates from the year 2000 to 2020.There'll be something for everybody in 2019, with total, annular, and partial solar eclipses - and total and partial lunar eclipses to look forward to. timeanddate has calculated these numbers using raw population data provided by the Center for International Earth Science Information Network (CIESIN) at Columbia University. * The number of people refers to the resident population (as a round number) in areas where the eclipse is visible. How Many People Can See This Eclipse? Number of People Seeing. Period between the beginning and end of the total phase Period between the beginning and end of all eclipse phases Percentage of the Moon's area covered by Earth's umbraįraction of the Moon's diameter covered by Earth's penumbra Quick Facts About This Eclipse Dataįraction of the Moon’s diameter covered by Earth’s umbra * The Moon was below the horizon in Odesa some of the time, so that part of the eclipse was not visible.Įclipse calculations usually accurate to a few seconds. From some places the entire eclipse will be visible, while in other areas the Moon will rise or set during the eclipse. Lunar eclipses can be visible from everywhere on the night side of the Earth, if the sky is clear. When the Eclipse Happened Worldwide - Timeline Actual eclipse visibility depends on weather conditions and line of sight to the Moon. Areas with lighter shadings right (East) of the center will experience the eclipse until moonset/sunrise. Note: Areas with lighter shadings left (West) of the center will experience the eclipse after moonrise/sunset. Missed total phase and part of partial & penumbral phases.
