Spacewatch Detects the WIND spacecraft

The object designated 2001 DO47 was discovered on 2001 Feb. 19 by R. S. McMillan with the 0.9-meter Spacewatch Telescope. It was detected as a trailed image because it was moving fast. The Minor Planet Center Electronic Circular (MPEC) 2001-D28 showed that the orbit was very similar to that of Earth and that the object would remain close to Earth for several months. The MPC continued to study the motion of the object as reported by many observers and has now concluded that it is the WIND spacecraft.
