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.
