Re: (meteorobs) British bolide last night - some videos & reports
- View SourceObservers,
I updated Bob's post about this fireball with a witness map.
Whenever I hear UK fireball I think about wet meteorites, but looking
at these reports its possible this may have made landfall NW of
There were several fragmentation & sonic boom reports.
Here is the witness map:

Reports of many different colors of this object have been received, with orange being most mentioned. The average brightness reported by witnesses was in excess of the light produced by a full moon. This fireball lasted an extraordinary long time, up to 20 seconds as reported by some observers.

We would not expect the general public to be highly accurate with magnitude estimates. This is one reason we listed magnitude estimates in at least two step increments. Still, a majority of contributors will choose an estimate of "brighter than the full moon" regards of the true brightness.A week ago, when the 4-day old moon was in conjunction with Venus, I posed a question to a number of people: "Which appears brighter to you, the moon or Venus?" Everyone who I asked said the same thing: "Venus." But on that particular night, the moon was actually brighter by some 3.5 magnitudes (a brightness ratio 25 times that of Venus). Of course, the reason that Venus was the overwhelming favorite was because it appears to the eye as a dazzling point, whereas the crescent moon's light was spread out over a half degree of sky.-- joe rao
