The absolute energy fluxes and relative intensities of emissions in the range of 3300 to 7300 A in the spectrum of the symbiotic nova HM Sge were measured during the 1984-1989 period. The gaseous component parameters during 1987-1988 were determined. The electron temperature of the gas was found to be decreasing after the outburst. The hot star's temperature is increasing, and is now about 150,000 K. The star's contribution to UBV radiation has diminished substantially over the past 10 years.
