The sun’s magnetic dynamo is weakening

Bruce Dorminey, writing on Forbes, says that astronomers now confirm that the Sun’s magnetic dynamo is likely to eventually disappear causing our star to lose its 11 year magnetic cycle

In fact, a billion years from now, they say, interplanetary spaceflight could become even more treacherous, since the Sun’s protective magnetic heliosphere would weaken or even disappear, leaving our solar system unshielded from incoming cosmic rays.

In a paper submitted to the journal Solar Physics, co-author Travis Metcalfe confirms that the Sun, a yellow dwarf (G-spectral type) star is indeed making a long term transition in its magnetic activity cycle.

Over the next one to two billion years, we have confirmed that the Sun’s magnetic cycle period will get longer before disappearing entirely.

CME impact possible on Nov. 8th

 

On November 5th, a magnetic filament on the sun became unstable and erupted.

The blast opened a fiery canyon in the sun’s atmosphere and hurled a CME toward Earth.

According to NOAA models, the plasma cloud could strike Earth’s magnetic field on November 8th, triggering G1-class geomagnetic storms and auroras around the poles.

Chance Of Magnetic Storms This Week

A large coronal hole is turning toward Earth, and it is spewing a stream of high-speed solar wind into space.

NOAA forecasters expect the stream to reach our planet on Oct. 25-26 with a 35% chance of geomagnetic storms when it arrives.

Storm levels could reach category G2, which means the glow of auroras might be visible not only around the Arctic Circle but also in northern-tier US states such as Minnesota and Michigan.

Where did all the sunspots go?

Something interesting is happening on the sun.
On Friday, June 3rd, the sunspot number dropped to 0, and the solar disk is still blank this weekend.

This is a sign that the sun is slowly shifting into a new phase of the solar cycle.

Learn more about the transformation on Spaceweather.com.
