Full-disk images in four colors at low-to-moderate phase angles, for monitoring spatial and
temporal variations in color and albedo. Surface monitoring frames are also useful for detecting
plumes on the bright limb.
Full-disk images in six colors for compositional mapping which might reveal absorption
features due to iron-rich silicates.
Images with Io illuminated by Jupitershine to search for night side brightenings and color
changes associated with condensing frosts or other phenomena and very low phase angle
observations to map regolith porosity variations.
