| Name | Han W |
| Experience Level | 2/5 |
| Remarks | This fireball is also recorded by amateurs at Wulanbutong County, and Mingantu County in Inner Mongolia and Beijing, the capital of China. This is also reported by a WeChat subscription article operated by the National Astronomical Observatories of China. See https://mp.weixin.qq.com/s/Im2ki18u9QJiSYnSeI_1JA (in Chinese) I heard that even a 14mm lens cannot capture the entire trail of this fireball. P.S. This object perhaps reduce its speed and accelerate again during its appearance. Seems like a hyperbola trajectory. |
