As December rolls in, skywatchers are in for a celestial treat with two prominent meteor showers lighting the night sky.

In its astronomical diary for December, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said the Geminids, an annual major meteor shower, will be active from Dec. 4 to 17.

The peak of the activity is expected to occur on Dec. 14. 

During this time, PAGASA said observers in dark and moonless locations can expect up to 120 meteors per hour.

The Geminids are known for their bright and fast meteors, making them a favorite among stargazers.

PAGASA explained that the parent body of the Geminid meteor shower is the asteroid 3200 Phaethon, which orbits the Sun in a way that generates this annual spectacle.

“The view of the meteor shower can be enjoyed once the shower’s radiant, in the constellation Gemini, rises around 7:10 p.m. above the eastern horizon. The radiant point will be at its highest in the sky at 2 a.m. producing its best display,” PAGASA said.

However, the presence of the waxing gibbous Moon will likely affect the visibility of the meteors, as the moonlight could obscure some of the dimmer meteors. 

To optimize the experience, experts recommend finding a dark location away from city lights, where the skies are clear and as moonless as possible.

Ursids

Following the Geminids, PAGASA said the Ursid meteor shower will be visible from Dec. 17 to 26, with its peak activity around Dec. 22.

This shower, produced by Comet 8P/Tuttle, is typically more modest regarding meteor count, producing up to 10 meteors per hour.

PAGASA said the best time to view them is before dawn, around 5 a.m.

Like the Geminids, the Ursids will be affected by the moon, as the waning gibbous phase of the Moon will interfere with the clarity of the shower. 

Nonetheless, the Ursids offer a serene and steady display for those willing to rise early and brave the cold December air.

PAGASA said both meteor showers can be observed with the naked eye, and no special equipment like telescopes or binoculars is necessary. 

To make the most of the experience, it is best to choose a location far from city lights, where the sky is clear and as dark as possible.
