Europeans are still trying to wrap their minds around what happened after sunset on April 23, 2023. Everyone knew that a CME was coming; photographers were already outside waiting for auroras. But when the auroras appeared, they were very strange."I had never seen anything quite like it," says Heiko Ulbricht of Saxony, Germany. "The auroras began to tear themselves apart, pulsating as they formed individual blobs that floated high in the sky."

"It literally took my breath away," he says. "My pulse was still racing hours later!" The same blobs were sighted in France and Poland, and in Denmark they were caught flashing like a disco strobe light.  Ordinary auroras don't act like this.

Indeed, "these were not ordinary auroras," confirms space physicist Toshi Nishimura of Boston University. "They are called 'proton auroras,' and they come from Earth's ring current system."

Most people don't realize that Earth has rings. Unlike Saturn's rings, which are vast disks of glittering ice, Earth's rings are invisible to the naked eye. They are made of electricity--a donut-shaped circuit carrying millions of amps around our planet. The ring current skims the orbits of geosynchronous satellites and plays a huge role in determining the severity of geomagnetic storms.

Sometimes during strong geomagnetic storms, protons rain down from the ring system, causing a secondary shower of electrons, which strike the atmosphere and make auroras. Earth-orbiting satellites have actually seen these protons on their way down. Ordinary auroras, on the other hand, are caused by particles from more distant parts of Earth's magnetosphere and have nothing to do with Earth's ring current.Mystery solved? Not entirely. "We still don't know why proton auroras seem to tear themselves apart in such a dramatic way," says Nishimura. "This is a question for future research."

"It was very exciting to watch," says Ulbricht. "I definitely want to see them again."

Good, because they'll be back. Solar Cycle 25 ramping up to a potentially-strong Solar Maximum next year. Future storms will surely knock more protons loose from the ring current system.

Here's what to look for: (1) Proton auroras tend to appear around sunset. Why? Electric fields in Earth's magnetosphere push the protons toward the dusk not dawn side of our planet. (2) Proton auroras love to pulse--a sign of plasma wave activity in Earth's ring current. (3) Proton auroras are sometimes accompanied by deep red arcs of light (SARs), the glow of heat leaking from the ring current system. These red arcs were also seen on April 23rd.

Solar Max is coming. Let the proton rain begin!

September 20, 2021 / Dr.Tony Phillips - NASA

Sept. 24, 2021: No solar storms? No problem. Earth has learned to make its own auroras. New results from NASA’s THEMIS-ARTEMIS spacecraft show that a type of Northern Lights called “diffuse auroras” comes from our own planet – no solar storms required.

Diffuse auroras look a bit like pea soup. They spread across the sky in a dim green haze, sometimes rippling as if stirred by a spoon. They’re not as flamboyant as auroras caused by solar storms. Nevertheless, they are important because they represent a whopping 75% of the energy input into Earth’s upper atmosphere at night. Researchers have been struggling to understand them for decades.

“We believe we have found the source of these auroras,” says UCLA space physicist Xu Zhang, lead author of papers reporting the results in the Journal of Geophysical Research: Space Physics and Physics of Plasmas.

It is Earth itself.

Earth performs this trick using electron beams. High above our planet’s poles, beams of negatively-charged particles shoot upward into space, accelerated by electric fields in Earth’s magnetosphere. Sounding rockets and satellites discovered the beams decades ago. It turns out, they can power the diffuse auroras.

The video below shows how it works. The beams travel in great arcs through the space near Earth. As they go, they excite ripples in the magnetosphere called Electron Cyclotron Harmonic (ECH) waves. Turn up the volume and listen to the waves recorded by THEMIS-ARTEMIS:

Above: A great electrical circuit in space powering diffuse auroras. ECH waves were sonified by NASA’s HARP (Heliophysics Audified: Resonances in Plasmas) software.

ECH waves, in turn, knock other electrons out of their orbits, forcing them to fall back down onto the atmosphere. This rain of secondary electrons powers the diffuse auroras.

“This is exciting,” says UCLA professor Vassilis Angelopoulos, a co-author of the papers and lead of the THEMIS-ARTEMIS mission. “We have found a totally new way that particle energy can be transferred from Earth’s own atmosphere out to the magnetosphere and back again, creating a giant feedback loop in space.”

According to Angelopoulos, Earth’s polar electron beams1 sometimes weaken but they never completely go away2, not even during periods of low solar activity. This means Earth can make auroras without solar storms.

The sun is currently experiencing periods of quiet as young Solar Cycle 25 sputters to life. Pea soup, anyone?  [Note: Solar Cycle 25 is accelerating.  MS}

End Notes:

(1) Why do these electron beams exist? Earth’s magnetosphere is buzzing with energetic particles. Many of them are captured from the solar wind. When these particles strike the top of Earth’s atmosphere (the ionosphere), they dislodge electrons. Electric fields, which form naturally in Earth’s spinning magnetosphere, grab the liberated electrons and accelerate them skyward in collimated beams.

(2) Why don’t the beams ever go away? Short answer: because the solar wind never stops blowing. Even when the sun is quiet, Earth’s magnetosphere is jostled and energized by the ever-present solar wind. As a result, electrons are always being knocked off the top of Earth’s atmosphere as described in Note #1. Although solar storms are not required for this process, solar storms can help. For instance, when a CME strikes Earth’s magnetosphere, the contents of the magnetosphere become extra-energized. Lots of particles furiously strike the top of Earth’s atmosphere, liberating even more electrons than usual. Earth’s electron beams can thus become super-charged. When the storm subsides, the electron beams may weaken, but they never vanish because even the quiet sun produces solar wind.

Although STEVE is not an aurora, he has an aurora side-kick: the "picket fence." Evenly-spaced blobs of green light often appear alongside or underneath STEVE during geomagnetic storms. Alan Dyer photographed these specimens on March 13th:

"STEVE put on a great show, appearing first as the characteristic purple arc then developing green picket fence fingers rippling from east to west," says Dyer.
What are these green pickets? A team of researchers led by Toshi Nishimura of Boston University may have found the answer. Using data from NASA's THEMIS spacecraft, they pinpointed STEVE's power source. More than 22,000 km above Earth's surface, magnetic explosions called "substorms" hurl streams of hot plasma toward Earth. When the streams reach an altitude ~250 km above Earth's surface, they begin to emit a soft-purple light. This is STEVE.
The same explosions spray energetic electrons toward Earth. The electrons move even deeper into the atmosphere, all the way down to 100 km, where they ignite fingers of green auroras. This is the picket fence.
So when you see STEVE, look for his sidekick as well. Sometimes the picket fence appears first, so one can herald the other. Either way, it's a beautiful show.

Unlike any other life on Earth, these extraordinary bacteria use energy in its purest form - they eat and breathe electrons - and they are everywhere.  STICK an electrode in the ground, pump electrons down it, and they will come: living cells that eat electricity. We have known bacteria to survive on a variety of energy sources, but none as weird as this. Think of Frankenstein's monster, brought to life by galvanic energy, except these "electric bacteria" are very real and are popping up all over the place.

Unlike any other living thing on Earth, electric bacteria use energy in its purest form - naked electricity in the shape of electrons harvested from rocks and metals. We already knew about two types, Shewanella and Geobacter. Now, biologists are showing that they can entice many more out of rocks and marine mud by tempting them with a bit of electrical juice. Experiments growing bacteria on battery electrodes demonstrate that these novel, mind-boggling forms of life are essentially eating and excreting electricity.

That should not come as a complete surprise, says Kenneth Nealson at the University of Southern California, Los Angeles. We know that life, when you boil it right down, is a flow of electrons: "You eat sugars that have excess electrons, and you breathe in oxygen that willingly takes them." Our cells break down the sugars, and the electrons flow through them in a complex set of chemical reactions until they are passed on to electron-hungry oxygen.

In the process, cells make ATP, a molecule that acts as an energy storage unit for almost all living things. Moving electrons around is a key part of making ATP. "Life's very clever," says Nealson. "It figures out how to suck electrons out of everything we eat and keep them under control." In most living things, the body packages the electrons up into molecules that can safely carry them through the cells until they are dumped on to oxygen.  "That's the way we make all our energy and it's the same for every organism on this planet," says Nealson. "Electrons must flow in order for energy to be gained. This is why when someone suffocates another person they are dead within minutes. You have stopped the supply of oxygen, so the electrons can no longer flow.  The discovery of electric bacteria shows that some very basic forms of life can do away with sugary middlemen and handle the energy in its purest form - electrons, harvested from the surface of minerals. "It is truly foreign, you know," says Nealson. "In a sense, alien."

The plane was being surrounded by positron-electron explosions causing peaks of high-energy, photon gamma rays - a clear sign of antimatter. The plane plunged downward and began to shake violently.   "I really thought I was going to die," Dwyer said.

So what is antimatter?  ExtremeTech explains that; "Antimatter is the name we give to particles with the same mass, but opposite charge, as the particles of which we are composed. When an antiparticle comes in contact with its corresponding "normal" particle, they annihilate each other and release gamma rays. In this case, the team detected a large number of positrons (the antiparticle of an electron) in that storm." But the positrons in the storm seemed to somehow steer themselves towards the plane, and what force did that remains a mystery.

It is possible the plane itself was interacting with the antimatter. Nature says that the positrons could have been annihilated in the immediate vicinity of the aircraft, or even on the plane itself. Aleksandr Gurevich, an atmospheric physicist at the Lebedev Physical Institute in Moscow, suggests that the plane's wings could have become charged, producing extremely intense electric fields around them, causing the creation of positrons.

The incident actually took place in 2009, but the story has only just come out, because scientists have been at a loss to explain what happened - and they still don't have all the answers. Dwyer, from the University of New Hampshire in Durham, told Nature; "This was so strange that we sat on this observation for several years." Scientists are sure the findings were not the result of some instrument malfunction. They have no doubt that Dwyer's plane correctly detected antimatter.

"The team's data are a "cast-iron signature" of positrons, said Jasper Kirkby, a particle physicist at the CERN particle-physics laboratory near Geneva, Switzerland.  However, the data which was recorded is puzzling. In particular, the size of the antimatter cloud was astounding. It measured between one to 2 km (1.25 miles) across - something never seen before, and experts still don't have an adequate explanation for that.  "We tried for five years to model the production of the positrons," and failed, says Dwyer.

Antimatter, in general, is extremely rare. When it enters the Earth's atmosphere, it usually comes in the form of cosmic rays from outer space. However, it is known that thunderstorms can also produce some anti-matter. NASA's Fermi Gamma-ray Space Telescope has recorded electrons in a thunderstorm accelerating to close to the speed of light. The electron-positrons then collide with an atom nucleus and emit gamma rays. (see video below) However, nothing has been seen on this level before.

What also baffles scientists is that, although the plane detected gamma ray spikes, the overall energy of the gamma rays present was insufficient to have produced the huge amount of antimatter recorded. So they don't know what mechanism was involved. Kirkby says that estimates of the size of the cloud might be too high, and that deeper investigations and experiments need to be made. Dwyer and his colleagues are sending special balloons into the center of severe thunderstorms to find out more.

Nature also reports that the US National Science Foundation plans to fly a particle detector on an A-10 'Warthog' into storms - something described as an armored anti-tank plane that could withstand the extreme environment.

The thing is - it isn't just the antimatter which is mysterious - but that we lack sufficient scientific knowledge of what happens in thunderstorms in general. Dwyer said; "The insides of thunder­storms are like bizarre landscapes that we have barely begun to explore."    Source

In theory light and matter are interchangeable [Einstein], but a practical demonstration was thought to be impossible.

Researchers have worked out how to make matter from pure light and are drawing up plans to demonstrate the feat within the next 12 months.

The theory underpinning the idea was first described 80 years ago by two physicists who later worked on the first atomic bomb. At the time they considered the conversion of light into matter impossible in a laboratory.  But in a report published on Sunday, physicists at Imperial College London claim to have cracked the problem using high-powered lasers and other equipment now available to scientists. 

"We have shown in principle how you can make matter from light" said Steven Rose at Imperial. "If you do this experiment, you will be taking light and turning it into matter."

The scientists are not on the verge of a machine that can create everyday objects from a sudden blast of laser energy. The kind of matter they aim to make comes in the form of subatomic particles invisible to the naked eye.

The original idea was written down by two US physicists, Gregory Breit and John Wheeler, in 1934. They worked out that - very rarely - two particles of light, or photons, could combine to produce an electron and its antimatter equivalent, a positron. Electrons are particles of matter that form the outer shells of atoms in the everyday objects around us.  But Breit and Wheeler had no expectations that their theory would be proved any time soon. In their study, the physicists noted that the process was so rare and hard to produce that it would be "hopeless to try to observe the pair formation in laboratory experiments".

Oliver Pike, the lead researcher on the study, said the process was one of the most elegant demonstrations of Einstein's famous relationship that shows matter and energy are interchangeable currencies. "The Breit-Wheeler process is the simplest way matter can be made from light and one of the purest demonstrations of E=mc2," he said.

Writing in the journal Nature Photonics the scientists describe how they could turn light into matter through a number of separate steps.

The process is one of the most spectacular predictions of a theory called quantum electrodynamics (QED) that was developed in the run up to the second world war. "You might call it the most dramatic consequence of QED and it clearly shows that light and matter are interchangeable," Rose told the Guardian.

Andrei Seryi, director of the John Adams Institute at Oxford University, said: "It's breathtaking to think that things we thought are not connected, can in fact be converted to each other: matter and energy, particles and light. Would we be able in the future to convert energy into time and vice versa?"

This artist’s impression shows a gamma-ray burst with two intense beams of relativistic matter emitted by the black hole.

Roughly once a day the sky is lit up by a mysterious torrent of energy. These events - known as gamma-ray bursts - represent the most powerful explosions in the cosmos, sending out as much energy in a fraction of a second as our Sun will give off during its entire lifespan.  
Yet no one has ever witnessed a gamma-ray burst directly. Instead astronomers are left to study their fading light.

New research from an international team of astronomers has discovered a puzzling feature within one Gamma-ray burst, suggesting that these objects may behave differently than previously thought.

These powerful explosions are thought to be triggered when dying stars collapse into jet-spewing black holes. While this stage only lasts a few minutes, its afterglow - slowly fading emission that can be seen at all wavelengths (including visible light) - will last for a few days to weeks. It is from this afterglow that astronomers meticulously try to understand these enigmatic explosions.

The afterglow emission is formed when the jets collide with the material surrounding the dying star. They cause a shockwave, moving at high velocities, in which electrons are being accelerated to tremendous energies. However, this acceleration process is still poorly understood. The key is in detecting the afterglow's polarization - the fraction of light waves that move with a preferred plane of vibration.

"Different theories for electron acceleration and light emission within the afterglow all predict different levels of linear polarization, but theories all agreed that there should be no circular polarization in visible light," said lead author Klaas Wiersema in a press release.   "This is where we came in: we decided to test this by carefully measuring both the linear and circular polarization of one afterglow, of GRB 121024A, detected by the Swift satellite."

And to their surprise, the team detected circular polarization, meaning that the light waves are moving together in a uniform, spiral motion as they travel. The gamma-ray burst was 1000 times more polarized than expected. "It is a very nice example of observations ruling out most of the existing theoretical predictions," said Wiersema.   The detection shows that current theories need to be re-examined. Scientists expected any circular polarization to be washed out. The radiation of so many electrons travelings billions of light-years would erase any signal. But the new discovery suggests that there could be some sort of order in the way these electrons travel.

Of course the possibility remains that this particular afterglow was simply an oddball and not all afterglows behave like this. 
Nonetheless "extreme shocks like the ones in GRB afterglows are great natural laboratories to push our understanding of physics beyond the ranges that can be explored in laboratories," said Wiersema.  ( The paper has been published in Nature. )

Electromagnetic radiation from today's X2-class solar flare had a significant effect on Earth's upper atmosphere. As a wave of ionization swept across the dayside of the planet, the normal propagation of shortwave radio signals was scrambled. In Alachua, Florida, electrical engineer Wes Greenman recorded the effects using his own shortwave radio telescope. Click on the frequency-time plot to view an animation (it takes about 4 seconds to start moving):

During the time that terrestrial shortwave transmissions were blacked out, the sun filled in the gap with a loud radio burst of its own. In New Mexico, amateur radio astronomer Thomas Ashcraft recorded the sounds. "This radio burst was a strong one and might be too intense for headphones," cautions Ashcraft.

Solar radio bursts are caused by strong shock waves moving through the sun's atmosphere. (Electrons accelerated by the shock front excite plasma instabilities which, in turn, produce shortwave static.) They are usually a sign that a CME is emerging from the blast site--and indeed this flare produced a very bright CME.                      www.spaceweather.com

Radio amateurs, have you heard any strange roaring sounds coming from the loudspeakers of your shortwave radios this week? It might have been the sun. "The Sun has been generating Type III solar radio bursts and they appear to be intensifying," reports amateur radio astronomer Thomas Ashcraft of New Mexico. "The strongest burst so far came at 2155 UTC on October 9th." Here it is as recorded on two radios at 28 MHz and 21 MHz:

Ashcraft recommends listening to the audio using stereo headphones. "Type III bursts drift downward in frequency," he explains. "In stereo you can hear the burst pass through 28 MHz first on one speaker and then flow through 21 MHz on the other sound speaker."

Type III solar radio bursts are produced by electrons accelerated to high energies (1 to 100 keV) by solar flares. As the electrons stream outward from the sun, they excite plasma oscillations and radio waves in the sun's atmosphere. When these radio waves head in the direction of Earth, they make themselves heard in the loudspeakers of shortwave radios around the dayside of the planet.

More radio bursts could be in the offing. NOAA forecasters estimate a 30% chance of M-class flares and a 5% chance of X-class flares during the next 24 hours.               www.spaceweather.com

RED AURORAS:  On October 2nd, a CME hit Earth's magnetic field, sparking a G2-class geomagnetic storm. Sky watchers on both ends of the Earth saw auroras; many of the lights were rare shades of red. Minoru Yoneto photographed this example from Queenstown, New Zealand:

"This is how the sky looked 11 hours after the CME impact," says Yoneto, who used a Canon EOS 6D digital camera to record the reds.

Auroras are usually green, and sometimes purple, but seldom do sky watchers see this much red. Red auroras occur some 300 to 500 km above Earth's surface and are not yet fully understood. Some researchers believe the red lights are linked to a large influx of electrons. When low-energy electrons recombine with oxygen ions in the upper atmosphere, red photons are emitted. At present, space weather forecasters cannot predict when this will occur.

During the storm, even more red auroras were observed over the United States in places like Kansas, Ohio, and Oklahoma. Browse the gallery for examples.  Realtime Aurora Photo Gallery      

THE INSTIGATING CME: The CME that hit Earth's magnetic field left the sun on Sept. 30th, propelled by an erupting magnetic filament.  SOHO photographed the CME at the start of its journey, racing away from the sun at 2 million mph (900 km/s):

The CME was impressive, but the underlying explosion was even more so. One movie [from NASA's Solar Dynamics Observatory shows the self-destructing filament in the context of the whole sun. Another movie zooms in for a close-up. It catches the filament ripping through the sun's atmosphere and leaving behind a beautiful "canyon of fire."

NOAA forecasters working through the government shutdown estimated an almost-even 45% chance of polar geomagnetic storms when the CME arrived. The CME justified those relatively high odds, sparking a G2-class geomagnetic storm around the poles.

To the human eye, a nearby flash of lightning looks blindingly white. But have you ever wondered what colors might emerge if the flash were spread out chromatically, like a rainbow? During a recent thunderstorm in Tarn, France, David Antao decided to find out. "I am an enthusiastic astro-spectroscopist," he says, "so I couldn't resist shooting some spectra." Here is the result:

"I found it really beautiful!" says Antao.

All of the colors of a rainbow are present in the lightning strike, but some colors are stronger than others. Red, green and blue emission lines zig-zag across the spectrum tracing the shape of the original bolt. These colors are mainly due to the recombination of electrons with nitrogen molecules broken apart and ionized by the searing heat of the lightning discharge. Lines from oxygen, hydrogen, and nitrogen oxides are present, too.

"By analysing this spectra, it is possible to determine the temprature of the lightning," notes Antao. "I am trying to do this now."
