    hello,
    
    [processing some not yet reported stuff]
    
    on Jan 2 Bram Dorreman reported 2 seconds interval flashes from
    TurkSat 1C or 2A during his geosat equinox observations of October 2002.
    
    On Jan 4, I tried both TurkSats to see if one of them was still showing
    flashes.
    Around 22h UT I saw two objects in my field of view, magnitude +12.5 and
    +13.
    
    No flashes were seen, so Bram probably had a favourite geometry to see
    flashes
    during the equinox of a reflective area which is otherwise not aligned
    properly.
    
    Be prepared for the next equinox run, which starts within some weeks !
    
    regards,
    
    Kurt
