The ISS against the Sun - from Spaceweather.com

To quote:

SPACE STATION TRANSIT: Yesterday, in Sonnenbuehl-Genkingen, Germany, amateur
astronomer Martin Wagner looked woefully out the window at his garden. Rain
was falling, thunder crashed, and clouds blanketed the sun. If this
continued, he worried, he was going to miss a very special event.

Namely, this:

"The clouds parted just in time for me to photograph the International Space
Station passing in front of the sun," says Wagner. "I used a solar-filtered
10-inch telescope and a Canon EOS 400D to make this 1/4000s exposure. After
the transit it became cloudy again, so this was a lucky shot!"

The snapshot crisply captures the station's newly-expanded silhouette: solar
wings almost as wide as football field, a science lab the size of a
Greyhound bus (Kibo), and three docked spaceships from Europe (Jules Verne)
and Russia (Progress 29 and Soyuz TMA-12). Add them all together and you
have one beautiful sunspot.
