Temporal variations in the solar submillimeter continuum
Abstract
The authors present observations of local intensity variations in the 300 - 800 μm solar continuum. Two-beam difference observations were used to determine power spectrum statistics of small temporal variations over the frequency range 0.1 - 20 mHz. The authors find a significant enhancement in spectral power (≡5K rms) for frequencies between 3 and 7 mHz. These and higher frequency variations are attributed to adiabatic response of the chromospheric medium to compression waves.
