People on the island of Bali and other parts of Indonesia will be greeted with beautiful views of the sky with the phenomenon of the lunar eclipse Perigee super blood moon, Wednesday, May 26, 2021.
“Bali is one of the areas that can observe the lunar eclipse,” said Head of Data and Information Division of the Center for Meteorology, Climatology, and Geophysics (BMKG) Region III Denpasar, Iman Faturahman, Friday, May 21, 2021.
A total lunar eclipse occurs when the sun, earth, and moon align.
“This happens when the moon is in the Earth’s umbra, which results in the peak of a total lunar eclipse, the moon will look red, known as the blood moon,” explained Iman.
He continued, because the position of the moon during an eclipse is in the closest position to the earth or called Perigee, the moon will look bigger than the normal full moon phases, so it is often called a super moon.
“So, the total lunar eclipse on May 26, 2021, is also known as the super blood moon, because it occurs when the moon in Perigee or the moon is in the closest distance to the earth,” he explained.
The phases or processes of a Total Lunar Eclipse that will occur in Indonesia on 26 May 2021 include:
Phase (P1) of the initial lunar eclipse starts at 16.46.12 Central Indonesian Time, it passes through the central part of Papua so that observers in Papua Province can witness the entire process of this total lunar eclipse.
Phase (U1) of the partial lunar eclipse starts at 17.44.38 Central Indonesian Time, crossing the islands of Sulawesi and Nusa Tenggara, so that observers in the eastern part of Indonesia, the island of East Sulawesi, and East Nusa Tenggara will witness this incident.
Phase (U2) of the total lunar eclipse begins at 19.09.21 Central Indonesian Time crossing Riau and West Sumatra Provinces so that all observers in Indonesia will observe the beginning of this totality phase, except in parts of Riau, West Sumatra, North Sumatra, and Aceh.
The peak phase of the lunar eclipse, which occurs at 19.18.43 Central Indonesian Time, will be witnessed in all parts of Indonesia, except in small parts of Riau, parts of West Sumatra, North Sumatra, and Aceh.
Phase (U3) of the total lunar eclipse ends at 19.28.05 Central Indonesian Time passing through North Sumatra, so that observers throughout Indonesia, except parts of North Sumatra and Aceh, can witness this phenomenon.
The phase (U4) of the partial lunar eclipse ends at 20.52.48 Central Indonesian Time in all regions of Indonesia.
Phase (P4) of the lunar eclipse ends at 21.51.14 in all regions of Indonesia.
“The entire eclipse process, from the initial phase (P1) to the final phase (P4) will last for 5 hours 5 minutes, and 2 seconds,” said Iman.
“While the total eclipse process, from the beginning of the total phase (U2), the total peak to the end of the total phase (U3) will last 18 minutes 44 seconds,” he continued.
BMKG will also observe the Total Lunar Eclipse on May 26, 2021, in locations throughout Indonesia using telescopes combined with detectors and information technology and disseminated via https://www.bmkg.go.id/gbt.
This total lunar eclipse can be witnessed if the weather conditions are cloudy and it is safe to be witnessed by the public with the naked eye, without having to use special eclipse glasses.
At its peak, in most parts of Indonesia, the position of the Moon is close to the horizon in the eastern part, allowing observers to capture the eclipse against the foreground of historical or iconic buildings.
“The public can follow this observation process by accessing https://www.bmkg.go.id/gbt. Communities who are on the coast or seafront need to be aware of the occurrence of sea tides that are higher than normal tides,” concluded Iman.
