The Earth has just suffered from a powerful solar storm: The scientist stands still

The danger is now not only from the ground but also from the distant Sun, for recently, a major cosmic weather phenomenon has just happened from the giant "fire pan".

The Sun has just glowed the X-level, or the largest Sun-fire, in the last 12 years, the largest in our solar system, the Space Weather Forecast Center ( SWPC) said.

The first morning light appeared on 5h10 in the morning on September 6, 2017, bearing the symbol X2.2 and only after that (8h03) a huge glow X9.3 was discovered, there was a 10 times greater plasma. Earth size.

If the X2.2 has the largest magnitude since 2015, then X9.3 is the biggest explosion recorded since 2006 (X9.0), both of which occur in an area called AR 2673. , here a few days ago also appeared bright in the M class (M - class).

Scientists predict the speed of these eruptions reaches 1,700 to 1,800 km / s!

The solar cycle usually occurs with an 11-year cycle, starting in 2008, when the Sunspot streaks quite calmly until recently. When sudden explosions occur at the surface of the Sun, it releases huge amounts of energy and takes hours after the explosion just dies.

Not only will this release heat, radioactivity and energy, this activity will cause solar storms with extremely energetic charged particles launched at a rate of 1 million km / h, then lose nearly 24 hours to reach Earth.

Accompanied by a series of related phenomena such as fire storms, fire ears, magnetic storms, solar winds and aurora on Earth. In addition, the explosion can cause a large plasma cloud called CME (coronal mass ejection).

"The explosion is also accompanied by radio radiation that we think may have a CME formed after that," said SWPC space scientist Rob Steenburgh .

"However, we still have to wait until we can take pictures of this event to have a firm answer."

Now scientists continue to monitor the Sun's activity through Coronagraph technology (Telescope to see the sun canopy - developed since the 1930s to study the Sun's shell) called SOHO / LASCO. .

The consequences that the Sun's explosion can cause are extremely energetic particles that will paralyze and even damage radio communications, GPS navigation systems and communication systems. of the navy or on satellites.

In addition, the electromagnetic storm also affects the Earth's electromagnetic field and causes power outages or danger to astronauts, NASA sensors .

Like the Richter earthquake scale, the Sun's explosions are similarly measured with A levels (smallest) and then B, C, M, X, respectively.

In particular, the magnitude of the following level is 10 times the size of the previous level. Example: A B-level explosion will be 10 times greater than level A, X level 10 times M level and 100 times higher than level C (this is the same as the Richter scale).
