Abstract
A synoptic campaign of Io and Io plasma torus observations were conducted near the Jupiter 2007 and 2008 oppositions. The 2007 campaign was contemporaneous with the HST Jupiter auroral campaign (PI: J. Clarke/Boston University). The observations were obtained from the NSO McMath-Pierce facility at Kitt Peak. The Io data are high-resolution (R 120000) spectra of the neutral oxygen 6300 Å emission taken on the main telescope with the stellar spectrograph. The stellar spectrograph, equipped with an image slicer, had a 5.2” x 5.2” field of view. Spectra with good signal-to-noise were obtained for a significant range of Io orbital and System III longitudes. The Io plasma torus data are ionized sulfur 6731 Å images taken on the west auxiliary through a 9 Å wide filter. Continuum images taken through an off-band filter improved the removal of the scattered light from Jupiter from the torus images. An update on the status of these observations and efforts to reprocess the entire Io NSO [O I] 6300 Å data will be presented.
