   NOTE: This JPEG image is made available in order to share with the
   public the excitement of new discoveries being made via the NASA/JPL
   Galileo spacecraft. Galileo scientists are in the process of
   calibrating and validating this data. The full digital image necessary
   for scientific analysis will be released within one year of receipt of
   this orbit's last data.

   Two New Hotspots On Io The Near-Infrared Mapping Spectrometer (NIMS)
   on Galileo obtained this image of half of Io's disk in darkness on
   September 19, 1997. This image, at 5 microns, shows several hot spots
   on Io, which are volcanic regions of enhanced thermal emission. The
   area shown is part of the leading hemisphere of Io.
   
   Two new hot spots are shown and indicated in the image (New, and
   Shamshu). Neither of these hot spots were seen by NIMS or the Solid
   State Imaging Experiment, (SSI) prior to this observation, becoming
   only recently active. Several other previously known hot spots are
   labelled in the image. Galileo was at a distance of 342,000 km from Io
   when this observation was made.

   mission for NASA's Office of Space Science, Washington, DC. JPL is an
   operating division of California Institute of Technology (Caltech).
