Re: Double flash from Iridium 65

I think that Willie is thinking that if the plane of the flat solar panel is
oriented at a right angle to the sun (for maximum absorption) that the light
would be reflected directly back toward the sun; then nobody would see it
except maybe during a total lunar eclipse. Can somebody clarify this?

I don't see why if the angles are right why you wouldn't get a reflection of
light off the solar panels. During the equinox, the geo sats flare because
because the solar panels reflect light towards us, due to the angles. People
have seen the flare from the iss thanks to the solar panels.

If you download rob matson's iridium flare program, you will see that it can
predict flares from the solar panels on the iridium satellites :)

So I am betting that what might have caused the second flare.
