There is currently a geomagnetic storm of up to level G5 going on, cuased by massive Sun eruptions.
NOOA's planetary K-index has rmaxed out at 9 three times already, which is the highest by far that I have ever witnessed.
More to come this weekend.
Power systems: Possible widespread voltage control problems and some protective systems will mistakenly trip out key assets from the grid.
Spacecraft operations: May experience surface charging and tracking problems, corrections may be needed for orientation problems.
Other systems: Induced pipeline currents affect preventive measures, HF radio propagation sporadic, satellite navigation degraded for hours, low-frequency radio navigation disrupted, and aurora has been seen as low as Alabama and northern California (typically 45° geomagnetic lat.).

Always the Sun. :-D
