A fireball at night, brigter than the venus - 20.7.2012 at 01.57 Helsinki Observation number 6379

Visibility III / V


I was just photographing night clouds when a bright line appeared in the zenith and the first thought was that the plane was going to ruin the picture. The camera was almost in the right direction, but autofocus would pull the lens out of focus. However, the image would not have been successful when the camera had all possible delays on due to time exposure. The cloudy mood flattened a bit after a handsome flash. I made a drawing of the flight path http://parpalahti.kuvat.fi/kuvat/Taivaan+vahti/Tulipallo_20jul12_1.57_ piirros_1000.jpg. The dimmer part of the same fireball's flight path had captured Panu Lahtinen's image. When the camera was pointed south, the bright final stage was left out. Takala's westward direction does not stem with his own and Väisänen's visual observation.
