They can to an extent. This is an X class flare with a CME, but nothing like the "carrington event" of 1859.. So don't go dig a hole just yet, but there can and will be some radio disruption. I noticed that the D layer absorption with way up in the northern latitudes.

Here is some more information... do not panic!
Solar Update
Here is the SolarHam space weather update for the morning of September 11th. Solar activity during the past 24 hours was strong. The largest and most noteworthy event was without a doubt the long duration X1.6 solar flare observed around region 2158 at 17:45 UTC. The flare was associated with Type II (3750 km/s) and Type IV radio emissions, a 10cm Radio Burst (TenFlare) lasting nearly an hour and measuring 1300 solar flux units, along with a full halo coronal mass ejection (CME). The majority of plasma appears to have a northward trajectory, however a still significant portion looks to be on line with our planet. Minor (G1) to major (G2-G3) geomagnetic storming will be possible within 24-48 hours thanks to this CME, in conjunction with an earlier CME associated with the M4.5 flare on Sept 9. Another isolated moderate to strong solar flare will remain a possibility today with regions 2157 and 2158 being the most likely source. All other visible sunspots are currently stable. A new sunspot in formation is now turning into view off the east limb, but is not yet considered a threat for strong solar flares. Energetic protons streaming past Earth remain above the minor (S1) radiation storm threshold this morning. These levels could persist until the expected passage of the CME events of Sept 9 and 10.

Thanks James. I'd not run across those rating systems before.
Here is a NOAA chart describing G1 to G5 geomagnetic storms:

G2-3 doesn't sound too bad by comparison.

To a hard drive that will fry also? hahahahha
Print out bank statements.
Back up to DVD.
Stock up on .22s!
AAAAAAHHH!!!! :donkey:
For your next reno project...

No, to a hard drive stored in a metal drawer or a DVD.

You all have neglected to realize THE MOST IMPORTANT LOSS WE WILL ALL ENDURE if everything electronic fries......
NO MORE TBN!!!!!
:shocked:
NO MORE TBN!!!!!
:shocked:
Well..... I'd expect that the 'Net will get rebuilt in the Valley (Silicon that is).
Obviously what we TBN'ers need to organize is a fleet of mechanically injected tractors so that we can (slowly :tractor: :tractor::tractor::tractor::tractor
transport redundant shielded HDs containing the TBN archives to Cali !We'd be today's Pony Express !

We want to get a trawler style boat and travel parts of Asia, N & S Pacific islands/counties, PNW, Alaska, US east coast and parts of Europe.
There is some risk with this plan both physically and financially.:laughing: But as our oldest says, YOLO! :laughing::laughing::laughing:
What worries me the most about this plan?
What DOES worry me is a lightning strike on or near the boat. Lightning DOES sink boats as well as destroy all/most/many electronics on the boat. The boat we want is metal which is supposed to minimize the chance of being hit and supposed to minimize any damage. Key words, "supposed to minimize." Minimize ain't zero probability.
Since boat diesels have to meet emission requirements this requires engine computers, a lightning strike can kill the engine, which could kill the boat and thus kill the crew. All the diesel engines for boats meeting Tier 3 are electronic controlled and if EMP kills the computer, so goes the engine. I talked to some JD marine engine guys about this and they confirmed my fear. There is no backup way to run the engine if the computer is fried. Furthermore, one of the consumables on emission controlled engines is not only fuel and air but now it is power. If the engines do not have power, they no workey. So if the engine computer some how survived the lightning hit but the alternator was fried, well you will be bobbing in the water.
This level of vulnerability is not a problem for a truck or tractor running on land, you just stop. On a boat this very well might cause a boat loss and maybe kill the crew.
I am trying to figure out how to build a Faraday cage around the boats helm station to protect the navigation, engine controls, and autopilot systems. Not sure how you could do this around the engine. The boat is built with lead around the engine room for noise reduction so maybe that along with the metal hatches and metal hull reduces the EMP vulnerability close to 0. Need to ask the builder about this....
From what I have read, a Faraday cage has to completely cover the systems to be protected. Any gap or whole can allow in the EMP. Since the helm station requires cable access for systems, sensors and power, one would have to be able to quickly disconnect these cables and close a cover over the cable opening as well as covering the helm itself. This would require you to go blind since your AIS, radar, engine controls, auto pilots, etc, would be under a cover and unpowered. Since the boat is all metal, car like if you will, in theory a lightning strike would flow on the outside of the boat pilot house and hull. So the crew would be protected from the power of the lightning but the EMP could be a problem due to window openings. I wonder if I can get gold embedded in the window glass like on the EA-6 Prowler or the rumored diamond coatings on the F18G Growler and F22?

- Pirates? Nope, you can pretty much avoid them, though areas in the PI that used to be safe, are a bit iffy today.
- Storms? Nope, These can be mostly avoided and the boat we would buy can handle any likely storm we would encounter.
- Reefs, Rocks, barely floating shipping containers? Sorta. The boat design we would buy has had a boat run up on a reef for a couple of weeks, one hit an ice berg, and another hit rocks at 13 knots with no damage. Having said that, it is best to avoid, reefs, rocks, icebergs, and shipping containers. :laughing:

Hmmm metal boat, metal hatches, lead around engine room, worries of EMP...from SUN I assume...not bomb.
since this is predictable, sounds to me like when an EMP is anticipated, just batten down the hatches, put aluminum foil over all questionable spots, ,make sure all metal shielding parts are electrically bonded together, and ride out the pulse.
I remember a show on TV about lightening researchers on a mountain top. Instrumentation showed when a strike was building, they lit off rocket with thin wire to guide the strike back down. How about such instrumentation, tow a dingy, have dingy remotely send up a rocket to snatch the lightening to it rather than your boat.
This is a long way from tractors!!
