The last Meteor Feast this year, the Gemini Meteor Shower, which is one of the three major meteor showers of the year, will be staged from Friday (December 13) night. Don't miss the last scene, let the editor arrange the best viewing place and beautiful shooting, and use the stargazing app!
"Gemini Meteor Shower" is one of the most impressive meteor showers every year. The Space Museum website shows that December 4 to December 17 is the active period of "Gemini Meteor Shower", and the peak period is at 3 am on Sunday (December 15). There are 140 meteors per hour in the zenith; the recommended observation periods are 9pm on Friday (13th) to 6am on Saturday (14th), and 9pm on Saturday to 6am on Sunday.

The most beautiful point shadow?
The Space Museum recommends using a wide-angle lens or a standard lens camera, which can be equipped with a fast film, the aperture is fully open, the lens is adjusted to infinity, the shutter is selected as the B button, and the tripod supports the camera to point at the sky area to be shot, and the exposure is from several minutes to one hour.
This fixed photography method will take meteors that occasionally appear in front of the lens into the film, and because the photos taken by this method will cause the image of the star to become a trail due to the rotation of the earth, it is also called star trail photography. But mention that everyone, the exposure time should not be too long, lest the star trails overlap each other, it is difficult to identify the constellation.

The sky is full of stars, but as long as you use the mobile app "Starry Night", you can calculate the positions of celestial bodies and constellations in real time. "Starry Night Walk" also has an augmented reality (AR) function. Just point the phone lens at the sky, and its electronic star map will indicate the names of celestial bodies and constellations seen on the screen, which is very practical.

Weather forecast
In terms of weather, the Observatory predicts sunny periods from Friday to Saturday (13-14) and cloudy days on Sunday (15th). The Space Museum stated that the local observation conditions were "poor" (the observation conditions are divided into five levels, which are "excellent", "good", "flat", "poor", and "bad").
But to mention everyone, the weather has been quite cool in recent days, and the lowest temperature is expected to be only 17 to 18 degrees from Friday to Sunday. When you look at the stars, remember to wear more clothes to keep warm.

Know more: Gemini meteor shower caused by asteroids
Most of the meteors are related to Mercury, but the "Gemini meteor shower" is different. It is caused by the Phaeton asteroid. It is currently known that there are only two meteor showers that are not caused by comets. As Fahe approached the sun, the rocks on the surface collapsed due to heat and scattered into orbital dust, explaining some of the source of the material that formed the "Gemini Meteor Shower".
