Io was a major target of New Horizons as it flew by the Jupiter system in February 2007. The Long-Range Reconnaissance Imager (LORRI), a high resolution panchromatic camera, obtained 190 images of Io at wavelengths from 400-900 nm. The Multicolor Visible Imaging Camera (MVIC), a near-infrared imager, obtained 17 color nighttime and eclipse images of Io. We have examined these images to determine which volcanoes were active. Furthermore, by combining data from multiple instruments, we will determine the eruption temperatures for several of the volcanoes. The total brightness of a volcano, along with its variation with wavelength and its temporal variability, yields insight into the eruption process of the volcano. Furthermore, the spatial distribution of volcanoes and its variation over time can yield insights into the tidal heating process. Io's volcanoes were not studied extensively between the end of the Galileo mission and the New Horizons mission, so these new data will expand the time-frame over which we have data.
