We present the thermal infrared (5–35 lm) spectrum of 956 Elisa as measured by the Spitzer Infrared Spectrograph (‘‘IRS’’; Houck, J.R. et al. [2004]. Astrophys. J. Suppl. 154, 18–24) together with new groundbased lightcurve data and near-IR spectra. From the visible lightcurve photometry, we determine a rotation period of 16.494 ± 0.001 h, identify the rotational phase of the Spitzer observations, and estimate the visible absolute magnitude (HV) at that rotational phase to be 12.58 ± 0.04.
