Palomar Observations of Impact Sites

We continued to monitor Jupiter using narrowband wavelengths between 2.0 and 2.35 and 3.0 to 4.0 microns. We obtained complete longitude coverage of Jupiter during July 22/23 UT. The following spots remained prominent: K, L, the G/S complex, R, Q, H, E/F, A and C. The K impact site exhibited complex structure, resembling a sideways and backward question mark, with a bright spot where the period of a question mark would be.

At 10 microns, impact sites L, G, Q, H, and K remained easily detectable and 8-14 micron low-resolution spectra were obtained of each. This is remarkable, as site G has completed 11 rotations since the impact.
After preliminary analysis of the 3.5 and 5 micron data from the R impact, we see the same double flash separated by approximately 60 seconds preceding the principal peak reported by the Keck group at 2.3 microns. Analysis of these data is continuing.
