Jonathan, I filmed several ones (including the so-called Darksat) 
Saturday morning during a pass high in the sky, from Rambouillet 
France between 04:59 and 05:18 UTC. Here is the synthesis:

I estimate the magnitude at culmination at 2.5 for the brightest 
(including Darksat) and 4 to 4.5 for the dimmest.
