The greatest solar storms in history

Updated on January 27, 2014

History of solar storms

As we go even deeper into 2013 with each passing day, solar storms are becoming a hot topic. We are becoming more aware of how dangerous for our technology or even health solar weather can be. Should we be afraid of geomagnetic storms? A quick look at the history of solar disturbances recorded on Earth shows that if not afraid, we certainly should be aware and prepared for solar storms of the future. Read on to find out more.

Solar storms - what are they?

In layman's terms - a solar storm happens when an exceptionally strong stream of solar wind arrives on Earth and messes with our planet's magnetic field.

Solar wind 'blows' all the time. It is simply a stream of charged particles constantly being ejected into space from the Sun's atmosphere. Earth's magnetic field is strong enough to protect us from most of ill effects of this 'bombardment' but during particularly intense assaults (caused, for example, by solar flares) it becomes disturbed, first compressing under stress, then snapping back with force to its original shape.

Ok, but what does all that mean to us here on Earth?

It could mean black outs. Geomagnetically induced currents present during solar storms can overheat power lines and equipment, in extreme cases 'frying' it.

It could mean havoc in navigation. Solar storms confuse GPS navigation systems so that they produce incorrect data. It's ok when you're missing your turn when driving, but what if an airplane crew relied on their GPS and believed they are a few miles higher than they actually are?

Solar storms are also confirmed to cause damage to satellites and disturb some radio frequencies. They also pose a radiation hazard to human beings not protected by the magnetic field (which in most cases means astronauts but very rarely can also mean commercial flyers). Some claim that geomagnetic storms have also direct impact on our health here on Earth (see the big link below).

Carrington Event

The inglorious title of the greatest solar storm in recorded history belongs to the Carrington Event, also known as Solar Superstorm or simply - solar storm of 1859. It followed a large solar flare, observed by Richard Christopher Carrigton (hence the name), which erupted on September 1st 1859. The Coronal Mass Ejection (CME) produced during the eruption reached the Earth in exceptionally short time - 17 hours - and caused strange things to happen on our planet during the first and second day of this memorable September.

Telegraphs all around the globe were the main 'victim' of the Carrington Event. Messages appeared to be running through the wires even when they were unplugged from power supply. Telegraph paper went on fire. Telegraphic machinery delivered some nasty shocks to its operators. Sparks were flying.

Northern lights (which are one more 'symptom' of a geomagnetic storm) appeared as fas south as the Caribbean. Imagine that - Aurora borealis on Cuba! Usually this phenomenon is restricted to polar areas of the world...

If a solar storm of this magnitude happened today, finantial losses incurred would probably run into billions.

The Transit of Venus Storm

November 17, 1882

Once again telegraphs went wild. The geomagnetically induced electric current was strong enough to light up electric lights. Aurorae borealis were seen all over Europe and Northern America.

The event was widely described in the contemporary press, so if you feel like digging through the archives, you're bound to find plenty of additional information there.

March 13, 1989 storm

This particular storm got its fame for frying up power grid of the Hydro-Quebec power station, which resulted in a black out lasting 9 hours and affecting 6 million people.

Satellites reported multiple anomalies, radio signals were blocked and Northern lights appeared as far south as Texas.

Bastille Day event

Here's one of more recent solar storms. According to the name, it all started on July 14, 2000, when the Sun produced a huge (X5) flare. It was the biggest solar event since the Quebec Blackout flare of 1989 and it caused a significant radiation storm here on Earth (airplane passengers got a radiation dose equal to one chest X-ray). A geomagnetic storm followed on July 15-17.

Solar storms and apocalyptic scares

We are nearing one of the greatest apocalyptic frenzy periods of our times - 2012 is upon us. I've lost count of Armageddon promises made so far (by, among others, Mayas, Hollywood film makers and rather doubtful 'scientists'). Solar superstorm that would destroy all electronics on Earth, thus launching a period of chaos and destruction, is one of the favourite scenarios, especially that we are approaching the peak of solar activity in the current solar cycle.

What is the likelihood of this dark picture becoming reality?

If you ask me - not too serious. Sure, we might get 'flared'. Sure, a solar storm of magnitude similar to the Carrington event would cause significant damage to power grids and bank accounts of energy supplying corporations (or insurance companies). Sure, it would be big and it would be messy. But apocalyptic? I don't think so.

Feel free to disagree (and express it in the duel module that follows) :)

If you want to find out more about geomagnetic storms - and to always know if there's one in the offing! - check out the best space weather website out there (see the big link below). I have it on my favourites list and visit it pretty much every day. It provides:

- reliable space weather forecasts

- detailed info on intensity and character of solar storms when they happen

- tips for sky gazers (i.e. when there is something worth seeing in the sky, like a meteor shower or an eclipse)

- beautiful pictures of Northern lights and other astronomical phenomena

Whichever it is, don't leave without saying 'hi' :)

Are you worried by solar storms?

      They happen. Sometimes, there are noticable effects. Just be prepared.

      Very good lens on chosen topic.

      Not really afraid of solar storms but certainly they do have impact on us on a larger or smaller scale, even if we are aware about or not.

      Great lens!
