We report 3 - 14 μm spectroscopy of the nova on Jan 31.45 2001 UT using BASS on the IRTF approximately one month after the object was discovered. The spectrum (W cm-2 μm-1) revealed only a smooth, featureless continuum that decreased monotonically with increasing wavelengths between 3 and 13.6 μm. Its slope is close to l-1.5, much shallower than the Rayleigh-Jeans tail of a black body. The spectrum was consistent with thermal emission from gray (constant)-emissivity dust whose temperatures ranged from around 280 K to upwards of 1300 K. IR magnitudes were L = 2.8, M = 1.6, N = -0.27, all +/- 0.05. The presence of such strong IR continuum emission so early after the nova's outburst suggests that this object is a recurrent nova and has undergone previous outbursts and dust formation events.
