Če koga zanima :) 

 

A Severe (G4) Geomagnetic Storm is highly likely to occur, possibly as early as later today and continuing through the weekend, according to the Space Weather Prediction Center (SWPC).

The exact timing of the storm remains somewhat uncertain, but at least seven earth-directed coronal mass ejections (CMEs) are currently in transit to Earth.

Rare occurrence in solar cycle
Since the beginning of the current solar cycle in 2019, only three Severe (G4) geomagnetic storms have occurred. The most recent was a brief event on March 23, 2024.

This is the first G4 Watch issued by the SWPC since 2005, highlighting the rarity of such events. The last Extreme (G5) event took place during the Halloween Storms in 2003.

The sun goes through 11-year cycles of activity, alternating between active and dormant. We are currently smack-dab in the middle of an "active phase", hence, why we see several sunspots on the surface of the sun.

 

One of these spots has caught the attention of scientists in recent days. Sunspot AR3664 is absolutely enormous, measuring about the size of 16 Earth's in diameter!

In the last few days, six coronal mass ejections (explosions of solar material, plasma) have burst from this sunspot sending billions of tons of coronal material whizzing through space at more than a million miles per hour. Because this sunspot is currently facing earthward, some of this CME is set to pass through our atmosphere.

Since the Sun is 93 million miles away, it takes a few days for the CMEs to reach Earth. Well, that time has arrived and the geomagnetic storm has begun.

 

 

Thankfully we do not believe that any of the geomagnetic activity will be intense enough to cause any major electrical grid problems on the Earth's surface.

This has happened as recently as back in 1989, when a very powerful flare caused a 9 hour blackout in the province of Quebec.

Back in 2003, we had flares intense enough to cause some damage to orbiting satellites and space shuttles.

As of now, it is believed that there has not been a big enough ejection from AR3664 to cause any major communication issues.

Posledica teh sončevih neviht severni sij v večjih predelih Murice in tudi UK

 

The Northern Lights will be visible on Friday and Saturday as far south as Liverpool in the UK, while also reaching more than a dozen US states. Depending on the intensity of the solar activity, there is a small chance that sightings will be possible throughout the UK.

 

In North America, the aurora borealis will cover all of Canada and stretch to several US states, including North Dakota, South Dakota, Idaho, Maine, Michigan, Minnesota, Montana, New Hampshire, New York, Vermont, Washington and Wisconsin.
