The eclipse begins on May 5, 2023 at 21:15 WIB with the peak of the eclipse at 23:24 WIB and ends on May 6, 2023 at 01:30 WIB.
“The entire region of Indonesia has a section. The penumbral lunar eclipse phenomenon can be observed in the region of Indonesia around midnight, which will occur on May 5-6, 2023.”
“The eclipse begins at 21:15 WIB on May 5, 2023 and ends at 01:30 WIB the next day and peaks at 23:24 WIB,” he explained, quoted from brin.go.id.
Rhorom explained that penumbral lunar eclipses occur when the full moon disk enters Earth's penumbra.
The penumbra occurs when only part of the sunlight is blocked by the earth.
In addition, Rhorom explained that this event was one of the results of the dynamic movement of the positions of the Sun, Earth and Moon.
A penumbral lunar eclipse occurs only during the full moon phase and can be predicted in advance because the positions of the moon, earth, and sun are nearly aligned.
“But all three are not aligned enough to produce a total lunar eclipse,” he explained.
A penumbral lunar eclipse occurs when some of the sunlight is blocked by Earth. In other words, the moon enters the penumbra of the earth. As the moon enters the penumbra, its brightness gradually decreases.
This penumbral lunar eclipse process is the position of the Moon, Sun and Earth in an alignment where the Moon enters only the Earth's penumbra.
“Therefore, when the eclipse peaks, the moon appears dimmer than the full moon,” he explained.
In addition, Rhorom also explained the difference between the umbra and the penumbra during a lunar eclipse.
“That is, if there is a portion of the moon that enters the umbra, then that portion receives no sunlight except for a small portion that is refracted by Earth's atmosphere, and conversely, the portion that enters the penumbra always receives nor sunlight.” . ,” he said.
