Observer
Name Dong H
Experience Level 4/5
Remarks The photo I subimtted is a stack of two consective images, when I was doing star trail photography. The camera settings can be found in the image data. The fireball was caught in two images, and there is a gap on the fireball, this is due to an interval of 1s of between two images. I didn't saw it from the beginning because I was looking at other direction. It is very bright, even in the almost full moon night and in the city center.
