    One more thing is obvious when I compare your report to my observation;
    I did not see it brightening to +1 as you saw.  So definitely observing
    angle makes difference over just a few hundred km.
    
    It was a fainter pass as the one I saw on May 22 through the SW but still 
    visible
    naked eye, although the sky was much clearer now. (On May 22 it was easy 
    visible
    through cirrus clouds with the naked eye.

    Yes, I'm surprised at this as well. I even stopped the imaging some seconds
    earlier, to dim the lights in the tracking scope so
    that I was able to watch better if I could see any flashes, but none....
    How much km are you north of me. Should it be the observing angle?
    I'm at (5048'N 554'E)

    Ralf, I am suprised by this, as on the same pass (!) it definitely was not
    stable for me: not visually and not photographically. It was definitely
    rapidly
    flashing...!
