Abstract • IR spectroscopy and photometry in the 0.8-2.4 and 3-14 μm regions are reported for seven dates between March 21 1998 and July 20 2000 UT. The shorter wavelength region displays a smooth continuum increasing to longer wavelengths that is indicative of the Wien tail of a Planck function. Only the He I 1.0830 line is present early and it shows a P-Cygni profile which later disappears. The long wave spectra show a smooth continuum between 3 and 13 μm that was well fit by a gray body at 1000 K. A weak, unidentified emission feature appears between 8 and 10 μm.
