In June 2008 Jupiter's Oval BA passed the Great Red Spot, providing a rare opportunity to observe the interaction of the two largest anticyclonic storms in Jupiter's atmosphere. Two of the imaging cameras on board Hubble Space Telescope, WFPC2 and NICMOS, were used to image Jupiter before, during, and following the GRS/BA passage in an effort to characterize changes in the nearby zonal wind field, internal vortex winds, and vortex cloud structure, including particle sizes, opacity and color. NICMOS images were acquired on 2008 May 16 and July 9 through filters centered on 1.45, 1.66, 1.87, and 2.12 microns. This set of filters was selected to probe a range in altitudes in the Jovian atmosphere from the ammonia cloud deck to the tropopause near 100 mbar. We examine the vertical structure of Jupiter's clouds in and around these interacting storms using iterative solutions from a forward-modeling radiative transfer algorithm. We discuss a comparison of the Great Red Spot, Oval BA, and surrounding regions as well as morphological differences seen between the NICMOS data and the WFPC2 data. We discuss specifically analysis of the properties of particles associated with a large red oval, which appears bright in the May 16 data, with particulates as high as those in Oval BA, and the remnants of this same oval after being distorted by passage between Oval BA and the GRS on July 1-3. These particles appear to be in the upper troposphere, as they are less distinguishable at wavelengths sensitive to deeper in the atmosphere.
Based on observations made with the NASA/ESA Hubble Space Telescope, obtained at the Space Telescope Science Institute, which is operated by the Association of Universities for Research in Astronomy, Inc., under NASA contract NAS5-26555. These observations are associated with program #GO/DD11498.
