If we were to get another solar flare of that size now, what would happen?
When a massive solar flare erupts on the sun, it can cause geomagnetic storms on the Earth.
The sun has gone more than two years without a significant solar flare.
FORBES: 'Revolution' Depicts America After an EMP Blast: But Is It Plausible?
On checking equipment in his laboratory, he was surprised to discover that the rate of radioactive decay changed before the solar flare.
There is a possibility that a powerful solar flare could cause serious harm to satellites, but such potential events are pretty rare.
FORBES: NASA Reports That Solar Flares Could Disrupt Power, Communications
If such a comet were the size of Hale-Bopp, Eichler says, the resulting solar flare would by far be the largest ever observed.
FORBES: Sun-Grazing Comets As Triggers For Electromagnetic Armageddon
Eichler thinks that such a sun-grazing comet may have triggered a large solar flare and cosmic ray-generating shockwaves as recently as 775 A.D.
FORBES: Sun-Grazing Comets As Triggers For Electromagnetic Armageddon
In February last year a large solar flare erupted, disrupting flights over Pacific, but the bulk of the material emitted by the Sun passed by Earth.
The storm started with a massive solar flare Tuesday evening and grew as it raced outward from the sun, expanding like a giant soap bubble, scientists said.
WSJ: Solar Flare: Sun Flare Leads to Solar Storm Reaching Earth
Another team of US physicists recently published a paper suggesting that an unusually large solar flare from the Sun could have caused the pulse of energy.
Military satellites and other electronic devices using carbon nanotube semiconductors will be able to withstand solar flare-ups and nuclear radiation from attacks that often corrupt data in standard chips.
After that, a solar flare damaged the craft's electronics, and its controllers decided on December 9th that they would not be able to put it into a Martian orbit.
ECONOMIST: The current crop of Mars missions has got off to a bad start
For example, on February 15 (the same day as a worrisome solar flare that fortunately missed the Earth) a new Congressional Caucus convened for the first time--the Congressional Caucus on EMP.
The main suspect is a solar flare: the sun was acting up at that time, and several other satellites (owned by Germany, Japan, NASA and Motorola) all failed at the same moment.
Scientists are gathered this week to discuss a relatively underappreciated threat to our well-being, the impact a huge solar flare (also known as a solar mass ejection (SME) or solar electromagnetic pulse (EMP)) directed at Earth could wreak upon our modern technology.
Trash tiles could, for example, bolster the space radiation shielding around the astronauts' sleeping quarters or perhaps a small area in the spacecraft that would be built up to serve as a storm shelter to protect crews from solar flare effects, NASA officials said.
MSN: NASA hopes astronaut trash can be used as radiation shield
White House Science Advisor John Holdren and Sir John Beddington, Science Advisor to British Prime Minister David Cameron, in a recent joint article "Celestial Storm Warnings" published in the New York Times, warned that a solar flare from the Sun could cause a great geomagnetic storm, with catastrophic consequences for the United States and the world.
