A fireball in a twilight sky - 9.1.2018 at 08.09 Akaa Observation number 69438

Visibility IV / V


Clearly green "hazy" big ball of light. The color tone is about the same as the "submit" button on this site. It seemed to "fall" at a rapid pace straight down to the horizon. Did not leave a tail behind.

Sphere size or brightness did not appear to change during observation. During the observation, the sky was clear.
