    I planned and observed Orion 3 again last night and am now convinced this
    was the UNID of 8/21/06 that many of you helped me find. With naked eye, I
    had two quick (~1 sec) mag +2.5 flares at 2:19:50 & 2:20:04, followed by a
    period (untimed) where it was barely visible (say +4.5), and then another
    round, mag 1.5 @ 2:21:50, and mag +2 @ 2:22:04 UT, with the same short
    period (~5 sec) of +4.5 mag. After this, couldn't find with 10 x 50's.
    
    Because a plane was slowly blinking through this area throughout the
    apparition, I'd have to say the first two timings are a little suspect. It
    did have a "video game" look to it that used to be funny but now isn't.
    
    Apologies to Bram Dorreman, I have no idea how to report that behavior in
    PPAS format. Didn't take positions, as it is well cataloged. A few more
    observations, and I'll try to figure out what phase angle it seems likely to
    flare at.
