Continuum energy distribution data for 48 Per are given in the 3200-8000 A optical region and are supplemented by data in the ultraviolet and infrared wavelength range. 48 Per is shown to exhibit an ultraviolet deficiency as compared to a normal B-star. The results also indicate an infrared excess emission in 48 Per. A T(eff) value is obtained which is much higher than the value expected from a star of this spectral type, possibly due to the increased opacity of the envelope and the resulting near-ultraviolet and near-infrared deficiency.
