Spectrum of Himalia from 2.2 to 3.8 μm. The shorter and longer wavelength NIRSPEC settings are shown as black and red, respectively. The spectrum is compared to a CM chondrite with a spectrum consistent with cronstedtite (blue)—a commonly occurring meteoritic phyllosilicate—and to a model of fine grained water ice frost overlying dark grains (green). Neither material provides a satisfactory match to the spectrum of Himalia.
