    Hi all,
    
    Dutch meteor observer Peter van Leuteren alerted me to a bright stationary 
    object appearing on his all-sky meteor fireball camera images the past few 
    nights, each time around 22:18 UTC in Ophuichus. It turned out that Bram 
    Dorreman also had noted the object visually. Brightness maximum around +2.5.
    
    In trying to capture the object yesterday evening for a photographic position 
    (Peter's all-sky images are not so suitable for high-res measurements), I failed 
    because, as it turned out, the object remained hidden just behind tree branches 
    for me.
    
    However, I accidentally captured a *second* geosat flaring to (near-) naked eye 
    visual magnitudes on the images, just to the west of where the other object must 
    have been  :-)
    
    Movie from twelve 10-second exposures spaced 1 minute apart each, can be seen 
    through a link given in the blogpost here (1.4 Mb animated GIF):

    It turns out to be Milstar 5 (2001-001A)
    
    I hope to capture the other object from a somewhat different vantage point this 
    evening (weather permitting) for an identification.
    
    Positional data on Milstar 5 in a separate post.
