The lunar eclipse is an event when the sun blocked the earth, so it does not all get to the moon. Previously, the same total lunar eclipse occurred 18 years ago, exactly on January 21, 2000. A similar eclipse will appear again in the same period in the future, which is February 11, 2036.
Head of the Meteorology, Climatology, and Geophysics Agency (BMKG) Dwikorita Karnawati, warned that the phenomenon of a rare lunar eclipse will occur on January 31.
This rare event can be observed from Indonesia clearly.
According to the US Space Agency (NASA), the phenomenon called 'Super Blue Blood Moon' is called a rarity because the total lunar eclipse occurs coinciding with the phenomena of 'supermoon' and 'blue moon'.
Supermoon.
Or the super moon, where the moon is full when the moon is in its closest position to the earth.
When the 'supermoon' event occurs, the moon will be only 358,994 kilometers apart from Earth, closer than its average distance of 384,400 kilometers.
Blue Moon.
Is the term used to signify the full moon of the second month in a month.
Super Blue Blood Moon 'in essence is a total lunar eclipse that occurs when the moon is in the closest position to the earth and appears in full (full moon).
When viewed from Indonesia, overall, eclipse events from the initial phase to the end will occur for about six hours, starting at 17:00 pm until 23:00 pm.
As the moon rises and is in full phase at around 20:30 WIB, January 31, 2018, the total lunar eclipse will be in the peak phase.
The event will last approximately 77 minutes, in which people across Indonesia will see the moon turning red.
As seen on the map, the entire eclipse process can be observed in the Pacific Ocean, as well as the eastern parts of Asia, Indonesia, Australia, and northwestern America, "Dwikorita said.
In Jakarta, Banten, West Java, Central Java, Yogyakarta, and throughout the province of Sumatra, the eclipse phase starts (P1) and the partial eclipse begins (U1) will be clearly visible because it occurs just above these areas.
