The more distant the moon is from the Earth, the longer it takes for it to travel along the Earth's shadow, subsequently resulting in a longer time to move out of it.
While a typical lunar eclipse usually lasts less than 2 hours, this week’s eclipse lingers for such a long duration because it comes just 41 hours after the Moon reaches its apogee-the farthest point on the Moon’s orbit around the Earth.
As this happens during the daytime for India, most parts of the country will not be able to catch it. At 5 pm, the eclipse will come to an end. It will then transition into the deep shadow for 3 hours, 28 minutes and 24 seconds until it exits the umbra at 4.17 pm. Because the darkening is so subtle, this phase might be difficult to detect without the necessary equipment.Īt 12.48 pm, the Moon will reach the umbra or the darker section of the shadow. Incredibly rare eclipse of November 19Īccording to the US space agency NASA, the eclipse on November 19 will take place in four main phases-around 11.32 am IST (November 19), the Moon will reach the penumbra or the lighter part of the Moon's shadow. When only a part of the Moon enters Earth's shadow, the event is called a partial lunar eclipse. In phases, the Moon travels through these shadows. During a lunar eclipse, the Earth casts two shadows on the Moon: the umbra, a dark, complete shadow and the penumbra, a partial outer shade. Therefore, a total lunar eclipse takes place only once in a few months for a brief period, usually for a few hours. This is because the plane of the Moon's orbit around Earth is slightly different from that of Earth's orbit around the sun.
#PARTIAL LUNAR ECLIPSE FULL#
A perfect alignment for an eclipse is rare despite the full Moon happening every month. (Sky & Telescope/USNO)ĭuring a partial lunar eclipse, the Moon will not pass entirely through the deepest area of Earth's shadow, known as the umbra, and most of the lunar face will turn on a vibrant red hue. Partial lunar eclipseĪ partial lunar eclipse. For a total lunar eclipse to occur, the Sun, Earth, and Moon need to be precisely aligned anything less than perfection results in a partial lunar eclipse or no eclipse at all. when the Sun completely illuminates the Moon’s surface, and the Earth comes right in between. Lunar eclipses, or Chandra Grahan, occur when the Moon is in its full phase, i.e. In modern times, we know that these are just events that occur as a result of the Earth orbiting the Sun and the Moon orbiting the Earth. In the past, solar and lunar eclipses scared people because they didn't understand what was happening. The event is also extremely rare, and to catch a similar phenomenon next time, one would have to wait for 648 years! What is a lunar eclipse? Next week, on November 19, during the wee hours of dawn, parts of Northeast India, along with the Americas, eastern Asia, Australia, and the Pacific region, will witness the longest lunar eclipse in 580 years. It’s the longest one in nearly six centuries! While November has many celestial events lined up one after another, this month's partial lunar eclipse is perhaps the most exciting.
