    Method: Canon Digital Ixus 400 + ASTRORECORD astrometric software.
    Camera at manual mode, "10 second" (= 10.7 second) exposure, wide field
    f2.8/7.41 mm.
    
    What these numbers mean:

    First true observations from my new polder outpost "De Wilck". Fair conditions 
    upon arrival (+6.5 in zenith), but thin ground fog developing and Lm varying 
    between +6.4 and +6.2 after that.
    
    Sat observations were done during breaks in Perseid meteor observations (130 
    meteors seen in 2.28h effective, of which 90 were Perseids)
    
    Cool -7 flare of Iridium 72 (98-032B). Iridium 14 (99-032A) flared seconds too 
    late compared to the prediction.
    
    Several strays seen, including a baffling stroboscopic flasher at 23:15 near 
    alpha And, and one that flared to -2 and then again to 0 at 00:26:00 near Polaris.
    
    The IGS 4r (07-005C) spectacularly flared to -1 at 00:42:00 UTC (Aug 12).
    
    Early evening obs from home (4353) will follow in a second mail.
