The variation in intensity of the solar x-ray resonance intercombination and forbidden lines of helium-like OVII with 2800 MHz solar radio flux is presented for three solar rotations. A high correlation r approximately equal to 0.80 exists between the intensities of all three x-ray lines and the 2800 MHz solar flux. The ratio of the forbidden to the intercombination line intensities is found to be essentially independent of long term solar activity. This ratio is used to determine upper limits on the coronal electron density and to make inferences concerning the change in density with solar activity. Author
