An unidentified object was observed plummeting from the sky in eastern China.

The video was filmed in the city of Jinan in Shandong Province on September 1.

The object ascended to a certain altitude before abruptly changing course in mid-air, eventually forming a distinctive angle with the ground before rapidly descending.

Remarkably, the video captures this descent without any accompanying sounds, save for the nighttime chorus of insects. Even the secretary-general of the Jinan Astronomical Society, Niu Guihua, who was present at the Qixingtai Observatory with colleagues at the time, reported not hearing any noise associated with the object's fall.

Niu Guihua further noted, "It's not an insect; flying insects can't move at such speed!" Based on the perspective from the video, it's inferred that the object approached from a distance, possibly hundreds of metres away from the surveillance camera.

Preliminary assessments have ruled out common astronomical phenomena such as meteors or meteorite impacts based on the trajectory of the object's fall.

Following the incident, observatory staff ascended the hill to search for any traces of the fallen object. As of now, no evidence of the impact has been located.

9月1日凌晨2:21，山东济南七星台天文台上空出现不明物体坠落。监控视频显示，该物体向上升空一定距离后，又在空中拐弯，最后和地面形成一定的夹角角度后急速坠落地面。

视频中该物体坠落时，除了夜间虫鸣之外，并无其它声音被监控相机录入。济南天文学会秘书长牛桂华表示，当时他与同事正在七星台天文台，也没有听到物体掉落的声音。

牛桂华还介绍，“也不是虫子，飞虫的速度也没这么快！”，根据视频角度推断，这一物体是由远而近过来的，离着监控摄像头最近距离感觉也得有几百米。根据物体坠落轨迹推断，初步排除了流星、陨石坠落等常见天文现象。

事发后，天文台工作人员上山去寻找，截止目前，暂未搜寻到坠落物体痕迹。
