对安静太阳中心的微波亮度温度光谱进行了新的测量，这些测量是在 1986 年至 1987 年太阳黑子极小期间的几个月内在欧文斯谷获得的。月球被用作主要的亮度温度标准，并对已知的月球边缘变暗进行了适当的校正。所得的亮度温度谱与之前的数据一致，但频率间的散射要少得多。
New measurements are presented of the microwave brightness temperature spectrum of the center of the quiet Sun, acquired at Owens Valley over several months during the 1986-1987 sunspot minimum. The Moon was used as a primary brightness temperature standard with appropriate corrections for the known lunar limb darkening. The resulting brightness temperature spectra are consistent with previous data, but exhibit much less frequency-to-frequency scatter.
