Planetwide Lights Out



Solar storms come and go. Usually they’re not too bad. But a couple of summers ago we near had our heads taken off.  A double “mass ejection” from the sun’s corona smashed past us.

We were on the far side of our orbit, conveniently out of the way.

A few days earlier? It would have been brutal.

The power grid, along with most electronics and computers, would have been made useless. We would have been back to the good old days when streets were lit with oil lamps and the houses were lit with flickering candles.

Except, who’s got oil lamps anymore? Who’s got candles?

In a paper in the journal Nature Communications Dr. Ying D Lieu and Janet G Luhmann estimated how long it would have taken to recover from our “sun spot hangover”. A long time, – years probably- before the lights would be back on everywhere.

The cost? In the trillions of dollars. The effect on our world?

No matter how hard I try, I can’t imagine!

Here’s the thing.

These solar ejections happen pretty often. Once-in-a-while there’s a big one. There was one about this size in 1859 when there weren’t any computers. The worst thing was some problems with the telegraph system; some operators got electric shocks.

If this latest “big one”, the 2012 mass ejection, had caught us dead center, it would have taken out our TVs, computers, phones,  vehicles, and all the rest of our high tech equipment. Even my furnace would have been creamed. My furnace has a computerized controller board which runs the controls; it also talks to me over wifi and sends messages to my phone. A disturbance  92 million miles away on the surface of the sun would have had me burning logs. My whole life would have changed.


There isn’t much we can do to keep the sun from being the sun. Stuff will keep flying off the sun and, someday, a mass ejection will have our number on it. What we can do, is get serious about monitoring for these conditions. With sufficient warning, maybe we can take steps to minimize the damage.

The drawing is mine.
