That's the basis for the concern about a large EMP-- a blast of charged particles travelling near the speed of light would toast any microchip and fry anything with a wire armature (motors. alternators, generators, solenoids). ..It's not known if Faraday cages would actually be of adequate benefit--not to mention that things you want to protect have to be in the cage at the time of the incident.Fascinating! A big one could cause all kinds of damage.
You should. In 1972, a solar storm set off all the sea mines the US Navy had deployed in Vietnam's harbors. Some others:I AM FREAKING THE ----OUT!
|Mar 1582||Great magnetic storms of March 1582||Prolonged severe-extreme geomagnetic storm produced aurora to 28.8° magnetic latitude (MLAT) and ≈33.0° invariant latitude (ILAT).|
|Feb 1730||||at least as intense as the 1989 event but less intense than the Carrington event|
|Sep 1859||Solar storm of 1859||Also known as the Carrington Event, the most extreme storm ever documented by most measures; telegraph machines reportedly shocked operators and caused small fires; aurora visible in tropical areas; first solidly established connection of flares to geomagnetic disturbances. Extreme storming directly preceded this event in late August.|
|Nov 1882||17-20 November 1882|
|Oct 1903||Solar storm of Oct-Nov 1903||An extreme storm, estimated at Dst -531 nT arose from a fast CME (mean ≈1500 km/s), occurred during the ascending phase of the minimum of the relatively weak solar cycle 14, which is the most significant storm on record in a solar minimum period. Aurora was conservatively observed to ≈44.1° ILAT, and widespread disruptions and overcharging of telegraph systems occurred.|
|Sep 1909||Geomagnetic storm of September 1909||Dst calculated to have reached -595 nT, comparable to the March 1989 event|
|May 1921||May 1921 geomagnetic storm||Among most extreme known geomagnetic storms; farthest equatorward (lowest latitude) aurora ever documented; burned out fuses, electrical apparatus, and telephone station; caused fires at signal tower and telegraph station; total communications blackouts lasting several hours. A paper in 2019 estimates intensity of −907±132 nT.|
|Jan 1938||25-26 January 1938 geomagnetic storm ("Fátima storm")|
|Mar 1946||Geomagnetic storm of March 1946||Est. Dstm of 512 nT|
|Sep 1957||Geomagnetic storm of September 1957|
|Feb 1958||Geomagnetic storm of February 1958|
|Jul 1959||Geomagnetic storm of July 1959|
|May 1967||||Blackout of polar surveillance radars during Cold War led U.S. military to scramble for nuclear war until solar origin confirmed|
|Aug 1972||Solar storm of August 1972||Fastest CME transit time recorded; most extreme solar particle event (SPE) by some measures and the most hazardous to human spaceflight during the Space Age; severe technological disruptions, caused accidental detonation of numerous magnetic-influence sea mines|
|Mar 1989||March 1989 geomagnetic storm||Most extreme storm of the Space Age by several measures; outed power grid of province of Quebec|
|Nov 1991||Geomagnetic storm of November 1991 ||An intense solar storm with about half the energy output of the March 1989 storm. Aurorae were visible in the US as far south as Texas|
|Jul 2000||Bastille Day event|
|Nov 2001||Geomagnetic storm of November 2001||A fast-moving CME triggered vivid aurorae as far south as Texas, California, and Florida |
|Oct 2003||Halloween solar storms, 2003||Among top few most intense storms of the Space Age|
|Nov 2003||Solar storms of November 2003||2021 study estimated Dstm of 533 nT|
# 1 & 8 are patently false. #2-7 = so what?And if you think that is bad, look up Earth's magnetic pole reversal!
1) The south pole has already left antarctica and the north pole is racing across the arctic ocean.
2) “Earth’s magnetic poles are getting ready to flip.” -Mission Manager, SWARM/ESA
3) The magnetic field began weakening in 1600.
4) The magnetic field weakened 10% from the 1800s to 2000.
5) Earth’s magnetic field was weakening 5% per century, but now is weakening 5% per decade.
6) The magnetic field is continuing to weaken rapidly.
7) Magnetic reversals can occur in less than 100 years.
8) Magnetic reversals lead to extinction events.
The first of the five "great extinctions" occurred 450M y/a. Since that time, the magnetic poles have flipped over 100 times.It will. Most of us will be here to see it. Maybe our grandchildren will not.
That flip will be literally instantaneous, so no increase in effective ionizing radiation exposure. There's better things to worry about.Unfortunately, when the poles flip the Van Allen belts collapse for a while. That leads to a higher rate of mutations, and sunburns, and cancer.
The flip is not instantaneous, nor does it keep the same strength. The VA belts will take quite a while to re-establish. THe rate of mutations in life forms will increase dramatically.That flip will be literally instantaneous, so no increase in effective ionizing radiation exposure. There's better things to worry about.
