I was spending Tuesday afternoon, as I often do, listening to a congressional hearing. Yesterday鈥檚 featured hearing was about the electrical grid and keeping the lights on in a disaster.

Of course, they discussed cyber security threats from China and Russia and domestic threats from our own home-grown yahoo attacking substations. But then Rep. Gary Palmer of Alabama, a former engineer, brought up a particularly ominous-sounding threat I hadn鈥檛 heard about before.

“Are you all familiar with the Carrington Event?” Palmer asked.

The Carrington event 鈥� was a solar flare. But not just any solar flare. And once I knew where to look, it was all over the internet.

“The 1859 Carrington event, the largest geomagnetic storm in history…it culminated in a gigantic cloud of highly charged particles,” different articles tell me.

It was named for an amateur skywatcher in London named Richard Carrington, who was observing sunspots September 1, 1859, when he was temporarily blinded by a flash of light.

And the next day 鈥� not only was there a brilliant Aurora Borealis extending as far south as Cuba, but the telegraph wires in London started catching fire!

He realized that the solar flare was responsible, and now it bears his name.

Today, NASA satellites routinely document these things, in fact, the latest Coronal Mass Ejection, as it鈥檚 called, will make its closest approach to Earth tomorrow. But the question at yesterday鈥檚 hearing was whether the grid can handle the kind of direct hit that happened in 1859. Rep. Palmer quoted a study by on what the after-effects of that would be today.

“Lloyds of London did an analysis of how it would impact North America if we had, or the United States in particular, if we had a guaranteed level of that,” Palmer said. “And they think that possibly as many as 40 million people would be without power for a few weeks, up to two years.”

So he put the question to Sam Chanoski of the Idaho National Laboratory, whose job is to know the weak points in the grid. Are you ready?

“Yeah, we have identified the most critical types of infrastructure, which are certain types of power transformers based on their design, so that we know where they’re installed, and with that, we can plan around them,” Chanoski said. “Sometimes you have enough time that you do have a number of hours where you can adjust the system to be less susceptible to something like this.”

I believe that means yes, they are ready, and if they can get a few hours notice, they can protect those weak points, and the lights will not go out for two years.

So I am very happy to hear that.

But I have my gas generator and my , just in case.

Although I鈥檓 not sure if I have two years of gas. Or a working typewriter ribbon.
