LINK<\/strong><\/a><\/p>\n“Ceres\u2019 surface has commonly been linked with carbonaceous chondrites (CCs) by ground\u2010based telescopic observations, because of its low albedo, flat to red\u2010sloped spectra in the visible and near\u2010infrared (VIS\/NIR) wavelength region, and the absence of distinct absorption bands, though no currently known meteorites provide complete spectral matches to Ceres. Spatially resolved data of the Dawn Framing Camera (FC) reveal a generally dark surface covered with bright spots exhibiting reflectance values several times higher than Ceres\u2019 background. In this work, we investigated FC data from High Altitude Mapping Orbit (HAMO) and Ceres eXtended Juling (CXJ) orbit (~140 m\/pixel) for global spectral variations. We found that the cerean surface mainly differs by spectral slope over the whole FC wavelength region (0.4\u20131.0 \u03bcm). Areas exhibiting slopes <\u221210% \u03bcm\u22121 constitute only ~3% of the cerean surface and mainly occur in the bright material in and around young craters, whereas slopes \u2265\u221210% \u03bcm\u22121 occur on more than 90% of the cerean surface; the latter being denoted as Ceres\u2019 background material in this work. FC and Visible and Infrared Spectrometer (VIR) spectra of this background material were compared to the suite of CCs spectrally investigated so far regarding their VIS\/NIR region and 2.7 \u03bcm absorption, as well as their reflectance at 0.653 \u03bcm. This resulted in a good match to heated CI Ivuna (heated to 200\u2013300 \u00b0C) and a better match for CM1 meteorites, especially Moapa Valley. This possibly indicates that the alteration of CM2 to CM1 took place on Ceres.\"\n<\/p>\n","protected":false},"excerpt":{"rendered":"
