Global oscillations have been observed in the high-frequency spectrum in velocity and intensity measurements, even above the acoustic cutoff frequency of the solar atmosphere. Recently it has been suggested that solar flares may be one of the mechanisms whereby these high-frequency oscillations are excited. Here we investigate the possibility of a causal relationship between high-frequency global oscillations and solar flares by correlating helioseismic data from GONG, MDI and VIRGO (SPM, LOI) with soft x-ray data from GOES SXI instruments.
