Re: They still can still flare, ie from solar panel - iridium next

I don't know their operating modes, but the "Iridium First" solar panels
had restricted mobility, so they use three different modes depending on the
Sun's angle from the group's orbital plane.
When near the orbital plane they constantly point near the Sun, and were
seldom directing flares to Earth.

Other controlled satellites are usually more flexible, and always flash
back towards the Sun.
Many geo sats have their panels towards the equatorial plane, and when the
Sun's direction is a slight way from Earth's centre they can send a flare
to ground. (Flaring geo seasons - spring and fall)

Uncontrolled satellites usually flash/glint - not flare.
