Earth is under a barrage of solar storms that could disrupt power and communications throughout Monday.

A major G3 geomagnetic storm struck the planet late Sunday night and forecasters with the National Oceanic and Atmospheric Administration (NOAA) have warned that a G2 storm is expected to follow today.

Geomagnetic storms occur when massive eruptions of plasma from the sun’s outer layer temporarily disturb Earth’s magnetic field.

At least 11 states will likely be affected by Monday's ongoing solar activity, including Alaska, Washington, Idaho, Montana, North Dakota, Minnesota, Michigan, Maine, Vermont, New Hampshire and Wyoming.

Transformers have been known to explode. I think I saw one in the distance as a kid during a storm with lots of lightning.

And a power surge could have taken down your modem.

Worth checking. Surge suppressors are usually reserved for expensive computers, but from your experience, doubling up with a computer might be advisable. The modem uses very little power.

Laptops, no prob.

Supersonic air craft. Perhaps they went up the Atlantic more?
