Oh boy!
 Good luck to our European friends...don't miss this if possible! I saw a booster reentry once & it's quite a show.

If I'm reading correctly, it'll be daylight over Spain and even more so if the reentry is one orbit later and happens to fly directly above my head. What can be expected in broad daylight?

Hum,
something like this meteor seen over Bogota Colombia on July 26th, 2007, at 18:10 local time... YouTube Video But it should be said that currently the satellite data is very unconstrained - so it could land anywhere along that orbit... |

That "meteor" looks an awful like a jet w/ a contrail to me, especially in the photos. Way too slow for a meteor and even for orbital debris IMHO.

Gordan you're right, is clearly a jet contrail... it happens often to see this effect at the sunset. Read also youtube comments...

Hum,
no fooling you guys....yes the meteor is a sunlit vapour trail...(i had been fooled by similar images like that before; but in this case in the blown up jpeg images the plane can be clearly be seen) Anyway... Re-entry update: 16th August @ 09:23 GMT ± 1 minute Predicted Decay Location 59° S, 329° E Inclination 98.3° Revolution Number 1093

Wow, this one's an oldie. Are there going to be any more refined reentry predictions as the event approaches?

@ugordan
Since the SL-6 is quite large ill watch the data and post an predicted landing site nearer the time |
