Abstract • IR spectroscopy and photometry in the 0.8–2.4 and 3–14 μmregions are reported for seven dates between March 21 1998 and July20 2000 UT. The shorter wavelength region displays a smooth continuum increasing to longerwavelengths that is indicative of the Wien tail of a Planck function. Only theHe I 1.0830 line is present early and it shows a P-Cygni profile which laterdisappears. The long wave spectra show a smooth continuum between 3 and 13μm that was well fit by a gray body at 1000 K. A weak, unidentifiedemission feature appears between 8 and 10 μm.
