These near-infrared (2.36 micron) images were taken by the South Pole Infrared Explorer Telescope (SPIREX) beginning at 2:21 p.m. (Chicago), 18 July 1994, at five-minute intervals. Jupiter's moons Io (far left) and Ganymede (top left) are visible. The impact site of Fragment G has rotated back into view and is visible as a bright spot near the planet's southern pole. SPIREX, built and operated by scientists at the University of Chicago, is funded by the National Science Foundation. The SPIREX team includes Mark Hereld, Hien Nguyen (at the South Pole), Bernard Rauscher and Scott Severson.
