KOMPAS.com – Stargazers in Indonesia can see the longest lunar eclipse of this century, which will last three hours and 28 minutes on Friday, November 19.
The National Institute of Aeronautics and Space (Lapan) said that 97.85 percent of the moon would be covered by the Earth’s umbra. The peak of the eclipse will take at 4.02 pm Western Indonesia Time, or 5.02 pm Central Indonesia Time, or 6.02 pm Eastern Indonesia Time.
A partial lunar eclipse occurs when the Earth does not completely block the sun. When it happens, part of the moon's surface enters the penumbral and the other part gets the light.
In Indonesia, the lunar eclipse will start at 1 pm Western Indonesia Time or 2 pm Central Indonesia Time, or 3 pm Eastern Indonesia Time. However, no region in the country can witness the penumbral phase as it is still below the horizon and has yet been risen.
The next phase of the partial lunar eclipse begins at 2.18 pm Western Indonesia Time, or 3.18 pm Central Indonesia Time, or 4.18 pm Eastern Indonesia Time. This early phase will also not be visible throughout Indonesia. Only some parts of Indonesia can witness the peak of the eclipse.
Where to see the lunar eclipse
The peak of the lunar eclipse can be seen from West Papua province (except Raja Ampat regency), Papua province, and some areas in Maluku province such as Tual, Southeast Maluku regency, and Aru regency.
The last phase of the eclipse begins at 5.47 pm Western Indonesia Time, or 6.47 pm Central Indonesia Time, or 7.47 pm Eastern Indonesia time. Almost all regions in the country can witness the last phase of the eclipse. This includes Papua island, Maluku, Sulawesi, Kalimantan, Nusa Tenggara, Madura, Bali, some areas in Java and Riau island, Bangka Belitung province.
