A fireball at night, as bright as a cresent moon - 18.8.2019 at 21.16 Varkaus Observation number 84882

Visibility IV / V

Veli-Pekka Hentunen, Warkauden Kassiopeia

The very bright point-like object moved about 90 degrees from south to downhill to the west. The object disintegrated at an altitude of about 30 degrees when looking west at the Härkämäki Observatory into three parts, each of which was very bright and greenish. About a second after the decay, the target faded. The brightness of the subject is difficult to assess but it was visible bright in the rather bright evening sky. I first saw a bright point-like object in the image of a webcam inside the Härkämäki viewing platform on a computer screen when the roof was open. When I turned to look southwest the item broke up.
