While waiting for my doctor, I snapped this with my iPhone. It was a translucent piece of plastic over an x-ray viewing screen - I imagine to gauge different shades of gray.

I frequently monitor Heavens Above to see if there's any upcoming satellite passes worth seeing. Tonight was one of the brighter showings of the International Space Station (ISS), with apparent magnitude -2.3, just dimmer than the maximum brightness of Jupiter. It started in the west-northwest, rising to 69 degrees in the south sky.
For whatever reason, I was waiting with my camera pointed too far to the east, trying to get a shot of the satellite rising over some houses. Right as I was scratching my head trying to find the thing, I finally saw (don't ask me how I originally missed it) the Big Dipper, which points me to the North Star (since I'm a star-gazing newbie).
Brief aside: the North Star is the center of this previous star trail shot I took last year.
Just as I realize I'm pointed in the wrong direction, I see the space station moving quickly across the sky. I was able to swing around and capture it as it faded into the Earth's shadow. In this shot, the ISS is moving downward as it fades into darkness.

View On Black
40D, Sigma 30mm f/1.4, 430EX flash
The window to the left provided most of the light here, but with harsh shadows on the right. I could either blow out the left side to bring the right in a little bit, deal with dark shadows on the right, or use a flash. The first two options are compromises - the latter, if done subtly, can still look like it wasn't used at all.
To pull this off, I used my camera-mounted 430EX flash, bouncing it off of the ceiling to the right, set at -1.5eV.
The flash was very dim compared to the sunlight, so it didn't affect a majority of the scene, but was just strong enough to brighten up the shadows a bit. At 0eV, the flash would probably have lit up the right side of her face to match the left, but that's just flat, boring lighting. I was able to keep the scene looking more natural by effectively taking the flash off-camera and increasing its size by bouncing.
Here's a test shot without flash to demonstrate how harsh the shadows are:
