Astronomy Science ~ Sunspot largest ever observed on the Sun in the last 20 years strong flare that fired back over the past week and spots that still produce powerful solar storms.

Currently, the large sunspots erupt with great flare peaked at 10:47 hours EDT (14:47 GMT). This causes flare radio blackouts on Earth, according to the National Weather Service Space Weather Prediction Center. These flares are X flare fourth (kind of the most powerful solar storms) are fired within a few days.
Solar Dynamics Observatory captures images from X1 class flare eruption on October 25, 2014.
On Sunday (26 October), the giant sunspots also releases a flare that peaked at 6:56 h EDT (10:56 GMT). Sunspots called Active Region 12192 (also known as AR 2192), also fired another strong flare on Saturday. Flare that occurred on this day and day of the week included in class X2 flare while Saturday's blast included in X1 flare.

X2-class solar flares release on October 26, 2014. NASA's Solar Dynamics Observatory spacecraft captured images of the explosion (bottom right).
"Flare X2 on Sunday was the third X-class flares within 48 hours, erupting from an active region on the sun's visible biggest in 24 years," wrote NASA spokeswoman Karen Fox is in an update yesterday (26 October). AR 2129 also issued an X3.1 class flare on Friday (24 October).

This active region is also spewing two M-class flares - middle-class solar storm - since Friday. The latest M-class flares (categorized as M6.7) erupted this morning at about 06:09 EDT (10:09 GMT).



Sometimes, large solar flares followed by large bursts of hot plasma known as coronal mass ejections (CME). Large CME can cause geomagnetic storms on the Earth's auroral light, but according to astronomer Tony Phillips at Spaceweather.com, previous storms released by sunspots currently have CME that follow.


If it leads to the Earth, X-class flares can be dangerous for astronauts and spacecraft that is orbiting the planet. Radiation can disrupt radio signals and communication, but solar flares can not hurt people on the earth's surface, according to Fox. The Earth's atmosphere acts as a protective barrier and us from harmful radiation.
