1991: President George Bush announced that the ground assault to expel Iraqi forces from Kuwait during the Persian Gulf War had begun; in the Middle East, it was already February 24.

1987: A supernova was detected in the relatively nearby Large Magellanic Cloud by an astronomer at Chile's Las Campanas Observatory; because it is so close (and actually visible to the naked eye), it became the object of intense study.

1848: John Quincy Adams, the former president of the United States, died at the U.S. Capitol, where he collapsed at his desk from a stroke; he had served in the House of Representatives since 1831.
