    I do not know whether or not this is significant, but Heavens-Above places a
    couple of Iridiums that were not predicted to flare, near the time and position
    you reported. Both were northbound.
    Iridium 65 (98021D / 25288) passed within about 10 deg of the position you
    reported, about 1 min later. Iridium 74 (98032D / 25345) passed a bit closer,
    but about 4 min later than you reported.
