The dark spots on Pluto were found by watching mutual occultations between Pluto and Charon. As you state, Charon was found around 30 years ago. This is why direct observation of Pluto's dark spots is my guess. (Spectroscopy would be an added bonus for sure!)
If the rotation between the two wasn't exactly synchronous, that should have fudged up the light curve-derived albedo maps of Pluto and Charon. Edit: On second thought, maybe it did. What's with those sharp longitudinal markings anyway? -------------------- -- Hungry4info (Sirius_Alpha)
