The South Pole Infrared Explorer (SPIREX) observed the fragment Q1 and Q2 impact sites rotating into view over Jupiter's limb at 2.36 microns. Conditions at the pole at the times of impact were not good, with clouds coming in and out. The Q2 impact was not easily seen, due to confusion with older impact sites. Q1 (lower left) appeared at 3:20 p.m. Chicago time, and was bright as expected.
The upper left frame was taken 20 July 1994 at 2:49 p.m. Chicago time. Subsequent frames are at approximately 5 minute intervals.
SPIREX team members are University of Chicago and Center for Astrophysical Research in Antarctica (CARA) astrophysicists Mark Hereld, Hien Nguyen, Bernard Rauscher, Scott Severson, Jamie Lloyd, John Briggs and Joe Spang (University of Wisconsin). CARA is a National Science Foundation Science and Technology Center.
