Fragment E Observation Reports


Impact e seen at 10 microns with CAMIRAS at NOT

Impact E has been seen at 10 microns with the CAMIRAS camera mounted on the Nordic Optical telescope at about 15h17min . UT. It was fainter than impact A seen yesterday. French-Swedish-Spanish team

Calar Alto

Calar Alto reports the detection of the fireball from fragment E with the 3.5m telescope at the 2.3 um band. The event was first noted at 15:17:30 and rapidly increased to more than 30 times the brightness of Europa. By 15:23, the fireball has dimmed to less than Europa's brightness.

Fragment E - No Optical Flashes

Fragment E (predicted at 1505 UT)

CCD imaging at Perth Observatory July 17 1450-1530 UT. Broad CH4 filter at 893nm, 2-sec exposures of limb of Jupiter (rest of Jupiter occulted by mask) with 60-70% duty cycle. No flashes or plumes were obvious in the raw data. Flashes greater than 25% of a square arcsec of Jupiter should have been seen in the raw data.
