Maybe someone with a very low lux surveillance camera and a semicircular mirror to point at for the needed wide angle can get a video of the effect followed by the Iridium flare that caused it. I once found a website that has a webcam that monitors the whole sky by looking downward at a semicircular mirror. It was used, as I recall, to observe aurora.
