We report 1-20 micron photometry of the interesting nova-like variable V838 Mon obtained 20-25 February 2002. This epoch corresponds to a local minimum in the visual light curve of the object. Modeling of the spectral energy distributions obtained during this epoch suggests the emission arises from two components, a T = 3000K blackbody and a T = 10,000K free-free component. The blackbody temperature is consistent with that reported by Lynch et al. in IAUC 7829. Our data do not indicate the onset of dust formation during this time.
