Infrared spectroscopy in the 0.8-2.4 and 3-14$\,\mu$m regions are reported for five dates between March 21 and Sept 30 1998, approximately 1275 to 1467 days after `outburst'. The shorter wavelength region displays a smooth continuum increasing to longer wavelengths that is indicative of the Wien tail of a Planck function or stellar continuum. Only a few lines are present including HeI$\lambda$1.0830 showing a P-Cygni profile. The long wave spectra show a smooth continuum between 3 and 13$\,\mu$m that was well fit by a gray body at 1000K. A weak feature between 8 and 9$\,\mu$m with the same shape as the SiO band seen in late type giants may be present.
