Images of CH₄ emission from Jupiter’s stratosphere (0.1−20 mbar, approximately) as described in Table 1. No perturbation from the impact (either the impact streak or crescent) is detected above the background noise and thermal wave activity. Panel a) shows an IRTF/MIRSI image from July 20, with a white arrow indicating the impact longitude. Panels b) and c) show a VLT/VISIR image from July 26, stretched to enhance contrast in panel c). Panels d)−g) are cylindrical reprojections of brightness temperature on four dates (UT times and instruments given in each panel). Any perturbation due to the impact would be expected at 55°S (planetocentric latitude) and 304.5°W (System III). All images were obtained in 7.9-μm filters, with the exception of the 7.7-μm filter on Michelle (July 22).
