A frequency-time diagram of global oscillations in the Sun as measured by SOHO. The colour-coding represents the strength of the oscillations. The bright horizontal lines are strongly correlated with solar flares, represented by the solar X-ray flux in the right panel. These lines are most prominent in the high-frequency region of the spectrum. The vertical line at 5.55 mHz in the left panel is an instrumental artifact.
