What is that thing ?
So, here is a series of pictures that my brother took about two weeks ago (2007/08/29, at 23:00 french local time).
He was going to sleep in his van when he saw a weird blinking/moving light at the horizon.
He put his digitalcamera (Fujifilm Finepix S5600) on his tripod, quickly configured it, extended the zoom to the maximum (optical + digital zoom) and took two series of photos with the burst mode. Then, he tried to quickly reconfigure his camera and to take one more manualy.
His tripod seems quite stable : stars don't move from a picture to an other.
As we can see thanks to the last picture (a photo of an other part of the sky took with the same parameters), the stars of the two series seems not to be "dead" pixels of the CCD sensor.
Known parameters :
shutter speed : 1/2.5s.
He says he doesn't know what it is.
With my other brother, we tried to find an explanation, but so far, we failed.
What do you think about this "UFO" ??
