Yep, it is amusing to several times find that image used as an illustration of a fireball, as it was positively identified as an airplane contrail. :lol:

Sorry, no automatic detection from Kopenhagen, and the archive exposures only shows the glare in thin clouds from the rising sun.

Congratulations to Thomas for an outstanding effort that was rewarded with a meteorite find long after we Danes had given up trying to find anything. With the difficult cloudy conditions, I am amazed that it was possible to pinpoint the fall location.

The data are: Long: 13.86344 Lat: 55.87282 Start Az 200 Alt 45 End Az 240 Alt 30 Most reports claiming a clear view of the fireball are from southern Sweden and Bornholm. Also ...

While the impression from the 400+ visual reports from Danish observers is somewhat confusing, telephone interviews with a selection indicate that the path went south of both islands of Falster and Lolland. So I think the path on the map posted by Przemyslaw is too far to the north. My interpretatio...

Hundreds of Danish visual reports are coming in, but most are just reporting a flash in the clouds. Below is a preliminary map of the observations: http://www.astro.ku.dk/~norup/webcam/obs20090117c.gif It is not always obvious from the reports if people has seen the actual fireball or lit-up clouds ...

Nice catch, and good performing camera.
Have you tried using the RAD Video Tools for converting the .MOV?
I worked fine for me, making an uncompressed .AVI, suitable for further processing.

Sure could be a meteor, but could also be much else.
There seems to be some powerful spotlights illuminating the building and flags from below - maybe a bird is flying through the light?

From Brorfelde (55.625N 11.663W), the azimuth angles are:
Start 155 deg, End 154 deg.
This places the fireball close to Berlin, but due to the short baseline and long distance, the north-south intersection is quite uncertain.

Got this one on the webcam from Brorfelde, as a flash without trail. Below is a map from a crude analysis - seems like this one was quite far away.

I have no had the opportunity to extract proper Alt/Az values. Jupiter is visible further towards east in the image. http://...
