Visibility IV / V
The ball of fire / light fell towards the horizon, eventually disappearing from view. The ball was followed by a vane that was not only bright, but also rippled with greenish tones of light (similar to the northern lights). However, this color clearly followed the ball, disappearing with the ball. I thought the fireball was pretty big. Clearly noticeable and rapidly advancing, appeared as if from scratch. The direction of the air was probably northwest.
