    Hi All,
    Follow-up to last night's post regarding an expected solar array
    flare from Iridium 8 -- I observed this bright flare naked-eye
    from Newport Coast, CA, for at least 15 seconds as it ascended
    below Mars.  In the bright twilight, only Mars and nearby
    Antares (+1.06) were visible in that part of the sky.  It was
    definitely brighter than Antares by at least one visual magnitude,
    but dimmer than Mars.  I'd estimate it peaked at about -0.5 --
    very close to prediction.
    I encourage people to try some of these Iridium solar array
    flares.  To give you an idea of the brightness enhancement,
    the predicted (diffuse) magnitude of Iridium 8 last night
    would ordinarily have been only +6.0 at the time.
