From: Multiple time-scale beats in aurora: precise orchestration via magnetospheric chorus waves
A direct comparison between the time-series of PsA luminosity and chorus intensity. (a,c) The blue line represents the auroral luminosity time-series at the MAX CCC point for (a) Case A and (c) Case B. The red line denotes the integrated wave power in the LBC wave frequency range (400 to 1200 Hz). (b,d) A zoomed-in view of the optical and wave data for (b) Case A and (d) Case B. The blue line represents the auroral luminosity time-series at the MAX CCC point while the red line denotes the integrated wave power over the LBC frequency range. The temporal variations in these two signatures are coherent (at a 0.28 s delay) for Case B.
