APOD: The ISS Expands Again (2011 Mar 09)

ISS with pedal power propulsion

Hello: When astronauts excercise do they generate electricity? Example; cycle wheel turns a gen set...

Why bother? They have abundant solar power.

Yes, but none of the solar power is directly used for propulsion

It's a great APOD and I became curious by what seems to be reflections of some sort behind the ISS.

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

Thank you Nick.
