Observations of the continuum microwave flux at 2.8 cm from quiet regions of the solar disk reveal low-amplitude quasi-periodic fluctuations at periods of 234 s and 150 s. For oscillating elements 10 arcsec in extent, the corresponding peak-to-peak temperature variations are 230 K and 190 K. The energy flux in the oscillations is estimated to be 250 erg/sq cm per sec, assuming they are caused by acoustic waves. If the oscillating elements are no more than 1 arcsec in extent, the energy flux is comparable to that required for coronal heating. No evidence is found for strong oscillations at periods greater than 250 s, although other authors have claimed microwave detection of strong fluctuations at periods of about 280 s and 400 s.
