Reports Report 3992o (Event 3992-2017)

Name Sophie W
Experience Level 1/5
Remarks This fireball was huge (about half the size of the moon) with a very very small glowing tail behind it. The color was bright green and it moved very slow compared to a shooting star (about the speed of a plane). The slow speed was very strange to me. But then after about 5 seconds, it disappeared behind the mountain range.
