The European aether? I read there are still railroads on 16.666 Hz in Europe. This was just quick experiment, more to come.
I just came home tonight inspired by the LIGO success and cobbled this together with no expectations. Just fun no more no less.
Sweet! That's awesome. I would have expected needing a lot more sensitivity.
I see no Michelson-Morley here though.
Thanks for that Scott. I was looking for something similar when I probed the ground in my yard with an ADC. What I found was mains AC noise, 60Hz and scads of harmonics.
FWIW, I used to sell very good power supplies for Schumann resonators. Yeah, I know, I know. But they sold like hotcakes. We tried the resonators in the office listening room. No one could tell any difference. But we were far out in the country, a long way from mains transmission lines and other EM pollution. All the resonator power supplies went to very urban environments. Never figured out if that was significant or not.

Chakras related or not, they are real and we can measure them.
They are been monitored as a reliable globe-wide lightning activity indicator.
Measured peaks vary a bit in frequency and Q and a lot in amplitude. Statistically they peak during local late afternoon.
A good read about underpinning atmospheric electric phenomena is this book

Update,
Tried again this morning slightly different and made sure shorting my coil made them go away. I'm slightly bothered that the lowest peak is lower in frequency than usually cited so I still need to verify that this is not a false alarm. But a set of noisy low Q peaks like this are easily observable in simple DIY experiments. Maybe George found the site, it's in Italy found under a search for ULF radio. They have several PC based options. The power output transformer backwards was my idea for a signal boost. The signal is in pico-Tesla range.
EDIT just noticed the peak at ~7Hz is moving slowly higher in freq (a good sign?).

Dumb question, but is the drift in the signal, or something 'settling' in your measurement rig?
An actual frequency shift would be hard to account for since the clock is crystal derived and percents of frequency shift are unlikely.
Here's the DIY site in Italy, lots of science fair material here. http://www.vlf.it/

It's actually pretty easy to duplicate some of the radio amateur experiments in the link above. They are usually interested in a wider frequency range, the lightening "whistlers" are neat.

There is not an exact frequency for the first S.W. mode.
2nd & 3rd mode also drift in frequency.
Just on time! I was reading this
ICS101 - Induction Coil
There are a couple of long investigations I have left unfinished due to my postponing building decent front ends for electric and magnetic sensors that pick up ELF to VLF signals from the air and route them through an acquisition module to a pc for recording and analysis.
This Italian site is the garden of Eden.
Of course I haven't yet managed to read the links Prof. George Google has found
It’s in the links. Read them or you’ll lose this Semester
SY, don’t tell me I haven’t tried.
