EU proponents should find this interesting.

Space physicists have long known that the Moon's gravity affects winds in Earth's ionized upper atmosphere. This means the Moon can actually modify electrical currents in the ionosphere, altering electromagnetic fields. The research team looked at data from NASA's Van Allen Probes and found that, indeed, electric fields reaching up into the plasmasphere appear to be modulated by lunar tides. Computer models suggest that these fields can shift the bulge to a 90 degree offset position and explain its daily and monthly variations.
The Spaceweather link has a synopsis with an informative 7-second video and the second link is to the scholarly paper with detailed information, analysis of satellite data, etc.
