Dr. Magnus and other crew members at the International Space Station are safe after taking shelter in the Soyuz "lifeboat" as a precaution:

The three American and Russian astronauts aboard the international space station took shelter in their Soyuz escape capsule briefly today to wait out the close approach of debris from an old U.S. commercial rocket stage, NASA said today.

The debris, about 4 inches long, whizzed within three miles of the orbital outpost at 11:39 a.m., CDT, causing no damage.
