5 km at the comet. Image motion tests at the end of the night through one telescope indicated that the seeing was 0.9-arc-sec FWHM. However, the combined beam of the ensemble of telescopes and spectrograph optics yielded stellar images 2 to 3 arc sec FWHM and 6 to 7 arc sec full-width at zero intensity so there was loss of light from the standard calibration stars through the 1-arc-sec-wide slit. The transparency of the sky was excellent during our observations.

The reflectance spectrum was derived by dividing the spectrum of the comet by the spectrum of the solar analog star and then normalized to unity at 5500 Å.
