Why bother? They have abundant solar power.

I did a simple "levels" adjustment in Photoshop to bring out the reflections better (Ctrl+L, then move the center triangle on the Input Level Bar to the left.
To my surprise, up came a big circular object right above the ISS and a smaller circular object to the upper right of the ISS.

Can anyone explain me what phemomena I am seeing?
Almost certainly, dust on the camera lens or low level flare in the optics
