NETHERLANDS FIREBALL: A fireball as bright as the full Moon startled observers in the Netherlands yesterday when it raced across the evening twilight sky. A lucky shot by photographer Jan de Vries at approximately 1658 UT caught the meteor in mid-flight:
"It was spectacular," says eyewitness Dominic Doyle of the European Space Agency in Noordwijk. "I estimate its magnitude to be about -12," (-12等)adds amateur astronomer Koen Miskotte, who saw it from the small village of Ermelo. Various observers report it breaking apart into as many as a half-dozen pieces, (可惜我没看到分裂)followed by sonic booms, low rumbles and shaking windows. A Royal Dutch Meteorology Institute listening post detected strong infrasound (low-frequency sound) waves, apparently confirming a high-altitude breakup event: data.
