Scientific paper

Coordinated measurements of fluctuations of the microwave radiation of the Sun have been made using the Arecibo and Effelsberg telescopes. At 4.75 GHz they have comparable beamwidths. The two outputs of nearly identical regions on the Sun generally turned out to be different. Significant correlation was found in only one run. No discrete periodic oscillation remained after cross-correlation. The possibly common part of the continuous fluctuation spectrum was extracted by the sample cross-correlation. These fluctuations were of amplitudes up to 500 Jy. A coherence length of 90 s was found. The suggestion is made that they may originate from jets recently observed in coronal EUV and that they may be of possible relevance to coronal heating.
