Well we can at least say that it wasn't CATASTROPHICALLY larger than predicted! Also the nearest ISS pass over the area is way off at the time of expected entry so there was no chance of observation from there...

Surprised I haven't seen any word of this from Aswan or Abu Simbel in southern Egypt. These would seem like the likeliest places where word/images/movies would have been returned and posted on the net.

That series of 10s exposures showing the thing 'speeding up' as it were - that's one of those rare astronomical observations that puts the Earth, the solar system, and the things flying around it into sharp '3d' context.

Maybe an indirect sighting of a webcam at El Grouna (middle east in Egypt): http://home.pages.at/thie/Asteroid/
In a German meteorite forum had someone contact to people in Egypt and they say it was great (more will be come I guess - the guy in the forum is sleeping now). Sadly Sadly their camera went off in waiting of the event and it was too late to start it again -------------------- |

Based on 26 optical observations, the probability of impact is between 99.8 percent and 100 percent,... so this thing dropped in the sea?

O.K. impact with Earth's atmosphere was for sure, but I guess there was some chance this meteorite ended up somewhere in the desert?
As the meteor appeared at nighttime it was spotted by an airliner... so maybe something made it through the atmosphere??? |

Spaceweather.com now has an update on an infrasound recording of the event.

No images/video after more than 24 hours. I guess it means none took any shot of the event?

Other than the webcam images in the German forum and this press article, nothing special I'm afraid...
