SECRET SPACE PLANE FLARES: The US Air Force's X-37B space plane is circling Earth and, although it is on a classified mission with an officially unpublished orbit, sky watchers have spotted it.

"I saw the X-37B from my home in Pasadena, California, around sunrise on March 31st," reports Anthony Cook of the Griffith Observatory. "The spacecraft's appearance was remarkable. When overhead it was a little brighter than a 2nd magnitude star with a slight yellow hue. Then it flared. As the X-37B moved toward the horizon it became silvery and brightened to around magnitude -6, far outshining Venus below it." The flare was presumably caused by sunlight glinting from some flat surface on the shuttle-shaped spacecraft, but no one can say for sure because it is a classified mission.
There are hundreds of satellites in Earth orbit; we cut through the confusion by narrowing the list to a half-dozen or so of the most interesting. At the moment we are monitoring a number of spy satellites, space shuttle Atlantis, the International Space Station, and the Hubble Space Telescope.
