    I managed to observe Soyuz TMA11 and its booster this evening. The booster 
    came first passing Alpha Ser at 17:55:01 UTC (10-OCT-2007). It flared 
    slightly irregularly to negative mags about every two seconds. I was 
    surprised about this - what I had expected was some much slower change in 
    brightness. Has anyone observed such quick flares of a Soyuz booster before?
    Soyuz TMA11 followed about 10 seconds after the booster reaching almost mag 0 
    close to Vega high in the sky when I lost track of it due to a roof getting 
    in my way.
