Full Moon Dimming Perseid Meteor Shower? BRIN Open Voice

Jakarta, CNN Indonesia

Phenomenon Full moon What will happen in the next few days is said to have an effect on another celestial phenomenon that will occur in the near future, namely meteor showers Perseid.

The peak of the Full Moon itself occurs on Friday (12/8), while the Perseid meteor shower will occur on Saturday (13/8) to Sunday (14/8).

The Full Moon this time is also quite special because it is at the closest distance to the Moon from the Earth or perigee, thus creating a phenomenon called a Supermoon.

According to Research Center for Space Research at the National Research and Innovation Agency (BRIN) Andi Pangerang, the intensity of the moon’s light will be able to affect the observation of meteor showers even though they are in opposite directions in the sky.

“Indirectly, the intensity of the Moon’s light can indeed affect the Perseid meteor shower, even though the Moon’s daily trajectory is in the southern hemisphere sky, while the Perseid radian point trajectory is in the northern hemisphere sky,” Andi told CNNIndonesia.com, Wednesday (10/8) .

However, the Perseid meteor shower only rises at 23.00-01.00, which is when the Moon has culminated. So when the Perseid meteor shower reaches its highest point, the Moon has set and the light is no longer disturbing.

“Because the Perseid radian point rises between 23.00-01.00 (according to their respective geographic latitudes), namely when the Moon is at its culmination, while when the Perseid reaches its highest point before dawn, the Moon has set, the moonlight does not necessarily reduce the intensity of the Perseid,” explained Andi.

The Perseid meteor shower itself has been active since July 17 and will end on August 24.

The peak of this celestial phenomenon will occur on August 13 with a meteor intensity that passes about 100 meteors per hour when the radian point is at Zenit.

When viewed from Indonesia, this meteor shower will have an intensity of between 36-61 meteors per hour due to the maximum height of the Perseid radian point between 21-38 degrees above the horizon.

In addition to the peak of the meteor shower, Andi said there are other best times to enjoy this celestial phenomenon, namely on July 20 to August 5 when the Moon reaches the final crescent phase to the early crescent and between August 19 to August 24 when the Moon reaches the final crescent phase until the end of activity. Perseid in 2022.

Perseid meteor shower is a meteor shower whose radian point comes from the constellation Perseus.

Perseid itself comes from the remains of comet 109P/Swifts-Tuttle dust. The speed of meteors in the Perseid meteor shower can reach 212,400 kilometers per hour.
