Northern Lights linked to whales stranding in UK

  Northern Lights linked to whales stranding in UK The Solar storms that produce the Northern Lights may have been to blame for last year's stranding of 29 sperm whales on beaches in the UK and other countries around the North Sea. The whales washed up on the Lincolnshire and Norfolk coasts in January and February 2016, and there were also beachings in the Netherlands, Germany and France.Scientists believe that whales - as well as other animals such as birds - use the Earth's magnetic fields to help them navigate when they migrate.

X-class solar flares are the strongest solar storms the sun experiences. A burst of solar material leaps off the left side of the sun in what’s known as a prominence eruption . Strong M8. 7 solar flare erupted from Region 2192 - watchers.news. No comments yet .

The frenetic activity should calm down soon hopefully.Between September 4 and September 11, NASA observed seven flares , all classed in its strongest “X” category, with the most impressive registering at X9.3, a very significant event.

The sun blasted out seven massive solar flares in as many days in an extraordinary period of space weather that has sparked stunning geomagnetic storms above the earth.

Between September 4 and September 11, NASA observed seven flares, all classed in its strongest “X” category, with the most impressive registering at X9.3, a very significant event.

The latest, at X8.2 also a significant flare, peaked at 12:06 p.m. EDT on Sept. 10. It prompted warnings of possible radio blackouts from the Space Weather Prediction Center, which also issued a geomagnetic storm warning for Wednesday and Thursday.

Biologists Have A Cosmic Explanation For Last Year's Mysterious Sperm Whale Strandings

  Biologists Have A Cosmic Explanation For Last Year's Mysterious Sperm Whale Strandings Last year brought what seemed like a disturbing omen to communities surrounding Europe's North Sea.&nbsp;Last year brought what seemed like a disturbing omen to communities surrounding Europe's North Sea: A whole lot of beached sperm whales. As Gizmodo reported at the time, the whales entered the sea's shallow waters, where their internal sonar-like systems stopped working, causing them to become stranded and die. But scientists didn't know why the whales entered these dangerous shallow waters in the first place.

A 10cm radio burst indicates that the electromagnetic burst associated with a solar flare at the 10cm wavelength was double or greater than the initial 10cm radio background. This can be indicative of significant radio noise in association with a solar flare .

The X9.3 solar flare was named by NASA as the strongest so far in the current solar cycle, a roughly 11-year period that began in December, 2008. The solar activity has been linked to increased aurora activity in the northern skies.

“The current solar cycle ... is now decreasing in intensity and heading toward solar minimum,” NASA said, “This is a phase when such eruptions on the sun are increasingly rare, but history has shown that they can nonetheless be intense.”

All the flares have emerged from the same “active region” of the sun, dubbed AR2673.

These events have been extremely intense, but none has caused serious disruption on Earth, and there’s no indication that the solar situation is going to get worse.

But that won’t always necessarily be the case in the future. In 1989, Canada’s Quebec state faced a nine-hour blackout from a solar event called a Coronal Mass Ejection.

Solar flares could also disrupt communications, including crucial satellite guidance system that could affect airplanes.

The two asteroids, collectively known as 288P, are locked in orbit around each other and are also spewing water vapor into space like comets.The two asteroids, collectively known as 288P, are locked in orbit around each other and are also spewing water vapor into space like comets (which originate in the region beyond Neptune). Many asteroids between Jupiter and Mars can claim one of those characteristics (orbiting one another or releasing vapor), but this is the first time that researchers have identified an object with both features, the researchers said.
