NASA captures images of strongest Solar Flare in 12 years

NASA captures images of strongest Solar Flare in 12 years

Spectacular aurora displays seen across the northern hemisphere in recent days have been caused by a huge solar flare with the energy of a billion hydrogen bombs, United Kingdom scientists have said. The radio black out from this particular flare has already passed.

The sunspot responsible for this morning's flares, active region 2673, is the smaller of two massive spots on the sun's surface, at only seven Earths wide by nine Earths tall, according to astrophysicist Karl Battams.

The sun unleashed monster solar flares that caused large-scale disruptions to Earth's magnetic field September 8 and produced stunning aurora over Antarctica. They often follow solar flares, and can cause geomagnetic storms. According to Space, the recent eruptions were classified as X-class solar flares, the most powerful category.

A CME is a large cloud of high energy particles ejected from the surface of the Sun when stored energy is suddenly released. The powerful flares were captured by NASA 's Solar Dynamics Observatory Satellite. 4, 2017. The last one occurred on September 8 while many more are expected to observe in coming days.

The solar explosions occurred towards the end of the active face of the current sun cycle.

A recent study of the last 30 years' worth of data on the solar cycle indicates that the magnetic field distribution, where a lot of the magnetic activity is recorded, had become thinner in recent years. A-Class flares are the weakest, while X-Class are the most energetic.

According to NICT, the solar flares that occurred around 9 p.m. on September 6 were about 1,000 times more powerful than normal. However, 3 hours later, a second flare erupted. However, intense explosions are capable of reaching the atmospheric layer which hosts Earth's Global Positioning System and communications signals. The magnetically filed activities result to an outward blast of energy that dramatically increases the solar surface temperature.

    Like Earth, the sun has a magnetic field, sort of like a looped rubber band: at one end is the south pole, the other the north. The path of the solar flare's CME is now being modelled to see whether some of the material could impact our atmosphere.
