An illuminated object was captured streaking across the sky in northern China.

The video was filmed in the city of Shijiazhuang in Hebei Province on October 25.

A student named Li accidentally captured the illuminated object when she was recording her friend on a playground.

According to Li, the UFO flew at a fast speed with tailing flame and gave off strange green light, which looked like a meteor.

A senior meteorite expert named Zhang Baolin at Beijing Planetarium said that the UFO seemed like a bolide. But it can only be confirmed after the debris is found.

A bolide is a meteoric phenomenon produced by the fall of a larger meteoroid.

When the meteoroids travel at high speed through the dense lower atmosphere of the Earth, large amounts of material volatilise and burn in the atmosphere, emitting a dazzling light that looks like a giant fire dragon and a thundering sound.

10 月 25 日晚 9 时 30 分许，河北石家庄一所大学多名大学生在操场看到一个不明飞行物划过天空，李同学正好用手机记录下这一幕。李同学介绍，不明飞行物的飞行速度较快，且拖着尾焰，发出奇怪的绿色的光芒，空中的尾焰还有分段迹象，较为罕见，感觉像是流星。
随后，山东宁阳、山西长治也有居民表示，称当晚 9 时 30 分左右，也在当地看到不明飞行物。这一幕被河北、山东、山西多地居民目睹。
北京天文馆资深陨石专家张宝林介绍，大家目击到的疑似一颗火流星，但只有找到了碎片之后，才能确定。
据了解，火流星是较大的流星体陨落时产生的流星现象。这种流星体在稠密的地球低层大气内高速运行时，大量物质在大气中挥发燃烧，发出耀眼的光芒，看起来像一条巨大的火龙，常伴有雷鸣声。
