Two of the three known soft gamma repeaters, SGR and SGR have a fairly small angular separation and are visible from Mt. Palomar. During the nights of 21–23 June 1997 we observed both in the mid-infrared using SpectroCam-10 on the 5-meter Hale telescope. We obtained excellent images of the counterpart to SGR in 6 bands using narrow filters from approximately 8 to 13 μm. The intensities in these 6 bands, summed over the two star-like components of the suspected counterpart, were all ∼2–3 Jy and together yielded the first mid-infrared spectrum of this object. A spectrum of the SGR counterpart was also obtained, but it displayed a significantly different shape and showed a source intensity of only ∼0.1 Jy. When combined with near-infrared and IRAS observations, the spectra imply that the counterparts of both SGRs consist of multiple components at different temperatures.
