This year’s Geminid meteor shower will be partially overshadowed by a bright moon, reaching its full phase on December 15th. The time of maximum activity is predicted for December 13th and 14th, favoring Asia but offering good viewing opportunities worldwide during these nights.
Due to the intense moonlight, only about 25% of normal Geminid activity will be visible. However, observers can still expect around 15 meteors per hour on the mornings of December 13 and 14 if they view during the predawn hours after the waxing gibbous moon has set.
The Geminid meteor shower is active all night long from most parts of the world, except in Antarctica where it’s not visible due to constant daylight. The radiant passes over near 2am local standard time for observers located near 30 degrees north latitude, making conditions favorable for viewing in the northern hemisphere.
Those in southern locations may see only morning activity, as the radiant is lower in the sky during this time. Nevertheless, with clear skies and a strong moonlit landscape, the Geminid shower presents an exciting opportunity to witness around 15 meteors per hour, surpassing most nights of the year.
Other notable meteor showers for the “meteor season” include the Ursids on December 22nd and the Quadrantids on January 3rd. While the Quadrantids will be stronger due to lack of interfering moonlight, their peak is shorter, lasting only around six hours, and may not offer the same global visibility as other showers.
