I was under a cloudless sky and pretty much on the center line (reflection angle 0.02 deg) for Iridium 24. It was also had a high elevation of 67 deg and range of only 840 km. It was significantly brighter than Venus and had a noticeable halo around it. I don't feel I can adequately judge how bright it was without having something to compare it against. I would guess somewhere in the -8 to -10 range (though I know others have figured -9 is about the limit). Two things struck me as unusual about this event. First is the more rapid-- compared to other flares I've seen--rise and fall of the brightness. Second is that I perceived a discontinuous drop in brightness after maximum. I'm wondering if this was when the antenna quit the direct reflection of the Sun and was left with just the specular reflection.
