    Hi all,
    KH USA 186 (05-042A, 28888) just made a beautiful slow flare here high in the 
    northwest, lasting some tens of seconds and reaching at least mag. -2. I first 
    saw it around the actual brigthness peak (21:13:06 +/- 3s UTC): when I looked up 
    from triggering the camera it already was very bright, then  started to fade 
    while the camera opened. This was the first time I saw it give off such a long 
    flare, instead of the very short glints I had seen it give off so far.
    Image can be seen here (crop, reduced resolution):
    Will report positions later, along with positions for USA 129.
    - Marco  :-)
