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 latitude.).
