I remember seeing a post about the Schumann being almost completely quiet a week or so ago. Could be something.
"Inverse problem"
One of the interesting problems in Schumann resonances studies is determining the lightning source characteristics (the "inverse problem"). Temporally resolving each individual flash is impossible because the mean rate of excitation by lightning, ~50 lightning events per second globally, mixes up the individual contributions together. However, occasionally extremely large lightning flashes occur which produce distinctive signatures that stand out from the background signals. Called "Q-bursts", they are produced by intense lightning strikes that transfer large amounts of charge from clouds to the ground and often carry high peak current.[26] Q-bursts can exceed the amplitude of the background signal level by a factor of 10 or more and appear with intervals of ~10 s,[30] which allows to consider them as isolated events and determine the source lightning location. The source location is determined with either multi-station or single-station techniques and requires assuming a model for the Earth–ionosphere cavity. The multi-station techniques are more accurate, but require more complicated and expensive facilities.
Q-BURSTS!!

In a theory known as the Harmony of the Spheres, Pythagoras proposed that the Sun, Moon and planets all emit their own unique hum based on their orbital revolution,[2] and that the quality of life on Earth reflects the tenor of celestial sounds which are physically imperceptible to the human ear.[3]
I am not a scienceanon. Or any type of math geometry. Until Q.
