The merger of the three white ovals into Oval BA in 2000, and its subsequent color change from white to red in 2005, appear to be loosely correlated to periodic interactions with the Great Red Spot (GRS). The interactions of these two largest vortices in the solar system - the Great Red Spot (GRS) and Oval BA - on Jupiter occur once every 18 months. Our data was acquired primarily at NASA/Infrared Telescope Facility (IRTF), with 1- to 5-micron imager, NSFCAM and its successor, NSFCAM2. We chose four canonical wavelengths that characterize the vertical structure of Jupiter’s atmosphere. Spectral decomposition of the geometrically-registered data identifies several physical changes on the planet: variation of global cloudiness increases during the interaction; the albedo of discrete clouds at different altitudes vary and there appears to be either enhancement or depletion of ammonia vertically in the atmosphere, especially after the color change in Oval BA in 2005. Analyses of the post-color change interactions of GRS and Oval BA in 2006 and 2008 indicate changes in thermal and albedo fields, with enhancement of ammonia in the perturbed region (Otto, Yanamandra-Fisher and Simon-Miller, BAAS, 2009; Fletcher et al., Icarus, 208, Issue 1). We shall present results of the current 2010 interaction, and its comparison to the previous interactions of the GRS - Oval BA. Our goals are to establish common attributes of the interactions in terms of physical changes in the local meteorology for both the unperturbed and perturbed states of the atmosphere, while differences in the interactions may highlight the temporal changes in the global atmospheric state of Jupiter.
