Researchers may have discovered a new method to predict solar flares more than a day before they occur, providing advance warning to help protect satellites, power grids and astronauts from potentially dangerous radiation.
The system works by measuring differences in gamma radiation emitted when atoms in radioactive elements "decay," or lose energy. This rate of decay is widely believed to be constant, but recent findings challenge that long-accepted rule.
The new detection technique is based on a hypothesis that radioactive decay rates are influenced by solar activity, possibly streams of subatomic particles called solar neutrinos. This influence can wax and wane due to seasonal changes in the Earth's distance from the sun and also during solar flares, according to the hypothesis, which is supported with data published in a dozen research papers since it was proposed in 2006, said Ephraim Fischbach, a Purdue University professor of physics.

Maybe they know it may be coming I saw this on the BBC website..
Solar flares can actually be predicted on Earth before they happen now because the rate of radio active decay changes before the storm.

Do you know what photons are? Can you explain how they can form a "belt"?
Just because the Wiki page has a bunch of bogus on it about the "new age movement" doesn't mean we aren't actually moving through a different part of the universe that contains a photon belt.
Um. The Sun is actually quite calm. Calmer than it has been in more than 100 years. Though it is following its 11 year cycle, the cycle is very mild as far as activity goes.
which I believe is the primary reason our sun has been so active lately.
Still don't understand what a solar flare is, huh? It is a burst of electromagnetic radiation. It is not directional. The Earth is hit by a flare which occurs anywhere on the side of the Sun which is facing Earth. The flare hit the SOHO satellite directly. The flare hit Earth directly. As shown above the effects on the upper atmosphere were actually that of an X45 flare. No EMP. No electronics fried. No people fried.
I just can't get a single thing through that thick little head of yours can i?
Solar flares do not affect electronics on Earth's surface. A solar flare will not hurt your iPhone (or you).
Geomagnetic storms do not affect electronics (unless they are plugged into an unstable electric grid).

Since you dont even know how the sun produces gas, I dont feel a need to reply back to you anymore. If you cant even understand that then you are simply incapable of understanding how Solar flares and photon belts work.
The magnetosphere provides a barrier between our planet and particles continually given off by the Sun's corona called the "solar wind." These particles constitute a plasma - a mixture of electrons (negatively charged) and ions (atoms that have lost electrons, resulting in a positive electric charge).
Plasma is not a gas, liquid, or solid - it is the fourth state of matter. Plasma often behaves like a gas, except that it conducts electricity and is affected by magnetic fields. On an astronomical scale, plasma is common. The Sun is composed of plasma, fire is plasma, fluorescent and neon lights contain plasma.
Mewaldt believes that all strong flares might emit hydrogen bursts, but they simply haven't been noticed before. He's looking forward to more X-flares now that the two STEREO spacecraft are widely separated on nearly opposite sides of the Sun. (In 2006 they were still together near Earth.) STEREO-A and –B may be able to triangulate future bursts and pinpoint the source of the hydrogen. This would allow the team to test their ideas about the surprising phenomenon.

Wiki is not a reliable source.
The article is saying that we would have a 30 minute warning before it ejects, not a 30 minute warning of it hitting the earth.

Worst case scenario, full frontal assault...my prediction.
Communications and power grid knocked out nationwide. Millions of homes and businesses on fire at the
point of electrical connection to the grid. Standstill traffic everywhere, A run on food supplies, chaos
and looting as alarms fail, police vehicles fail, and government services fail.
Faraday cages will protect your electronics, but with no electrical grid or working satellites it will
be awhile before that preparation will help you. Most vehicles will not run without repair and there will be
a stoppage in the supply line from farm to store. People will be stranded...older cars that operate
and bicycles will sell for many times their value, and those guns we use to protect ourselves
will be very valuable as well....

Obviously some of you don't understand CMEs. If a CME is directed straight at the Earth, we have a huge stress on the magnetosphere. Northern lights really fire up and some go woowoo. An X level CME gets through the magnetosphere and can affect electronics. Not the initiial blast, which could be at light speed, and we will detect, but the actual Mass of the CME. Notice I said Mass. There is an actual ejection of MASS in a Coronal Mass Ejection. A small one is not a problem. A big one is.
The X-28, revised to X-45, was not pointed at Earth, but we did see it, and it was so big it wiped out our sensors. Prior to that CME, the definition of CMEs had as a definition that an X CME of over 30 would cause deaths on Earth because the magnetosphere would be wiped out and hard radiation would be allowed to come through.
X-Ray Flare Classification
Solar flares are classified based on their x-ray intensity. A series of letters and numbers is used to classify the energy level of an x-ray flare.
C = 1.0x10-6 (W m-2)
M = 1.0x10-5 (W m-2)
X = 1.0x10-4 (W m-2)
Notice that this CME is even larger than the Sun itself, which is represented by the white circle in the middle of the frame. Solar flares and coronal mass ejections often occur together, but each can also take place in the absence of the other.
