The 19 July 2009 impact on Jupiter captured worldwide attention, and sparked a highly successful WFC3 imaging program during SMOV, with the last Hubble image acquired on 8 August. Continuing ground-based observations have revealed significant differences between this event and the Shoemaker-Levy 9 impacts in 1994: a single impact event offers a chance to study the longer-term evolution of the impact debris field without confusion due to overlapping aerosol debris clouds, and this debris field evolved more slowly than the SL9 sites. Initial analysis of our first data set reveals possible curved streamlines that correspond to no known tropospheric vortex. To constrain the stratospheric velocity field traced by the impact-generated aerosols, we request 10-hour separated data (a temporal sampling rate which we could not obtain during SMOV) that are crucial for tracking coherent albedo features. We also requested (but were not granted) a single orbit of high-resolution near-infrared images. These data would have provided the sharpest visible and near-infrared images of the site, providing context for the ongoing worldwide campaign of lower-resolution ground-based observations.

The first two orbits are consecutive, imaging the eastern and western areas of the impact site on Jupiter. Multiple frames in FQ889N will deliver the highest-contrast images of the impact site, allowing a full mapping of the area and providing short-interval image pairs for velocity retrieval. The second pair of orbits follow one Jovian rotation (~10 hours) after the first pair. This pair will afford the highest-precision velocity fields to be constructed by tracking coherent features over the important 10-hour sampling interval. Additional filters will be used to measure spectral properties and constrain vertical distributions of the impact-site aerosols. 0 false 0.0 0.0 false false false false false false SUPPORTED SOLAR SYSTEM PLANET JUPITER IMPACT SITE EASTERN REGION STD=JUPITER TYPE=PGRAPHIC,LONG=280.0,LAT=-57.0 CML OF JUPITER FROM EARTH BETWEEN 245.0 305.0 EARTH SOLAR SYSTEM PLANET JUPITER IMPACT SITE WESTERN REGION STD=JUPITER TYPE=PGRAPHIC,LONG=320.0,LAT=-57.0 EARTH SOLAR SYSTEM PLANET JUPITER IMPACT SITE EASTERN REGION STD=JUPITER TYPE=PGRAPHIC,LONG=280.0,LAT=-57.0 EARTH Using ephemeris for target 12045-01-JUPITER-IMPACT-EAST-1 ephemeris data for target 12045-01-JUPITER-IMPACT-EAST-1 does not cover planning interval.
