    I was at 43.263 N  79.8103 W  observing the ISS pass overhead at 21:06:42
    EDT  -  21:12:26 EDT (8/19 1:06UT-1:12UT)
    As ISS approached the Lyra part of its pass overhead, a flare appeared
    travelling S to N at about the 50 degree altitude level, passing above the
    Aquila constellation, about 1/3 of the way towards Lyra,... the flare
    started at about 155 degrees azimuth , travelling S to N and ending at about
    80 degrees azimuth yet staying fairly level at about 50 degrees. The flare
    passed mere seconds before the ISS, such that they almost intersected at the
    same point in time just above the Aquila constellation. I'm not very good at
    judging magnitudes, but the ISS was  definitely the brightest object with
    this flare being less than the ISS, but much more than the brightest 3 stars
    (1 in LYRA, and 2 in Aquila).
    Heavens-above showed nothing that coincides with this flare.
    I showed the flare lasting about 10-15 seconds, and as I said, it was just
    ever so slightly the first to cross the intersection point.
