Extract

NGC 7027 was observed on two nights, 1976 May 18–19 and 20–21, using the 36″ telescope of the KAO. A medium resolution, two channel, Helium-cooled grating spectrometer was used to observe the bands, 16-23μ (Δλ = 0.5) and 20-38μ (Δλ = 1.2). The beam size was 30″. A nearly flat smooth continuum over the entire band was observed with a peak intensity of 7 ×10−16 W/cm2μ between 20 and 25μ.
