NOAA — Sun spews out steady stream of solar flares for week

For over a week now, our sun has been spewing out a continuous stream of solar flares, causing NOAA Space Weather Prediction Center to issue a geomagnetic storm warning on Tuesday and Wednesday.

Symposium warns we could have another 'Carrington event'

We have talked about solar flares before, and generally, we think of them as creating beautiful auroras seen close to the Earth's poles. But what if one of these flares was a "super flare?" What could it do to the Earth?

CME hits Earth — massive geomagnetic storm shows in bright lights

Two nights of spectacular aurora borealis — the result of a massive coronal mass ejection that made a direct hit on Earth's magnetosphere, supercharging our magnetic shield — trumpeted the occurrence of a fierce geomagnetic storm.

Op-Ed: Is the sun getting ready to turn out the lights?

The sun sure has been heating up things around these and other parts lately. The Lower-48 hasn’t seen this much sun in at least a generation. Here in Texas, too much sun and too little rain teamed up in 2011 to give us the worst drought in history.

Video: NASA tracks latest major Sun flare, rated X1.8-class

NASA has released videos of the coronal mass ejection (CME) that blasted off the Sun on January 27, 2012. The videos were taken by the Solar and Heliospheric Observatory (SOHO) and the Solar Dynamics Observatory (SDO).

Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however — when intense enough — they can disturb the atmosphere in the layer where GPS and communications signals travel.

NASA's Solar Dynamics Observatory captured this image of a solar flare – as seen in the bright flash on the right side – on Sept. 10, 2017. The image shows a combination of wavelengths of extreme ultraviolet light that highlights the extremely hot material in flares, which has then been colorized.

Within a class there is a linear scale from 1 to 9.n (apart from X), so an X2 flare is twice as powerful as an X1 flare, and is four times more powerful than an M5 flare.
