1. This is a time-lapse video of the night sky over Mt. Sobaek, which was taken when I was staying at SOAO, Sobaek Optical Astronomical Observatory, Jan 28, 2012. The tail-like shapes are not meteors; they are just the digital effect. A bright meteor can be seen near the peak ahead at 1 min, and another fainter meteors also can be seen. Trails moving slowly and not following the one which the entire stars are making are those of air-crafts or satellites.

    It was made from 957 photos taken from the midnight till the early morning. Notice the flashlights of hikers approaching along the mountain trails.


    소백산 위로 쏟아지는 겨울 밤하늘.
    바로 앞에 있는 건물이 소백산 천문대이며, 그 너머 봉우리에 있는 것이 기상레이더 기지입니다. 별이 유성처럼 쏟아지는 것처럼 보이는데, 이것은 디지털 효과일 뿐 유성우와는 관계가 없습니다. 유성은 1분쯤 기상레이더 기지 위에 밝게 지나가는 게 보입니다. 그 시기를 전후해서 어두운 유성들이 같은 방향으로 하늘을 할퀴고 지나가는 게 보입니다. 기원이 비슷하다는 것을 암시합니다만 딱히 연관된 유성우는 없습니다.

    이 동영상은 2012년 1월 28일 오전 1시 8분부터 아침 7시까지 촬영한 957장의 사진을 이용하여 제작한 것입니다. 새벽 4시가 넘을 무렵에는 아침 해를 보려는 등산객들의 불빛이 등산로를 따라 다가오는 것이 보입니다.
