The first infrared observations of the peculiar object HM Sagittae were made by Davidson et al. (1978). The spectrum of the observed intense infrared radiation indicates that the origin of the radiation is related to the presence of dust grains. Kwok and Purton (1979) have shown that the emission of graphite particles at a temperature of 800 K involves an infrared spectrum closely matching that of HM Sge at wavelengths greater than 1.5 micrometers. However, the flux observed at 1.25 micrometers appreciably exceeds the flux density computed for a graphite envelope. The present investigation is concerned with visual and infrared photometry of HM Sagittae obtained in 1980-1981. The significance of the new data is discussed, taking into account the possibility that the HM Sge system might contain a cool, variable component.
