A photographer recently snapped images of vibrant green streaks of light hanging apparently motionless in the star-filled sky above a U.S. mountain range. The eerie light show may look like auroras, but it’s actually an even rarer phenomenon.

Aaron Watson captured the stunning display near the West Elk Mountains in Colorado. The streaky emerald lights emerged just before midnight on June 21 and lasted for around 2 hours, during which they slowly shifted across the sky, Watson told Live Science in an email. Similar but less-intense versions of these lights were also spotted in other parts of Colorado, according to Spaceweather.com.

At first, Watson believed the lights belonged to noctilucent, or night shining, clouds, which were forecast to become more frequent in June and July this year. But as the vibrant colors emerged, this seemed unlikely. He also speculated they could be a slow-moving auroral display or a related phenomena, such as STEVE or a stable auroral arc that was set off by a solar storm bashing into Earth.

However, there was no solar storm at this time. Instead, the lights are the result of a phenomenon known as “airglow,” which is triggered in the upper reaches of Earth’s atmosphere by less-extreme forms of solar radiation. Airglow is rarely seen from the ground, but it could become a more common sight in the coming months and years as solar activity ramps up, Spaceweather.com said.

Experts recently revealed to Live Science that the upcoming peak of solar activity, which was due to arrive in 2025 and be relatively weak compared with historic past peaks, may actually arrive as early as the end of 2023 and be more active than previously expected. The sight of such vibrant airglow further supports this hypothesis. 

A study published March 2021 in the journal  JGR Space Physics, revealed that airglow has historically been most visible during previous solar maximums — the period of the roughly 11-year solar cycle where solar activity peaks and the sun releases more radiation and solar storms. Tracking changes in airglow can therefore help track solar cycle progression, according to NASA. (Auroras also become more common during the solar maximum.)

Airglow and auroras are both triggered by solar radiation hitting Earth, but the mechanisms behind them are very different: Auroras form when powerful streams of solar radiation, known as solar wind, or fast-moving clouds of magnetized plasma, known as coronal mass ejections (CMEs), smash into Earth’s magnetic field. This temporarily weakens Earth’s defensive shield, enabling solar radiation to penetrate deep into the atmosphere and excite air molecules so they emit bright, dancing colors.  Image 1 of 2The green color of this airglow is caused by excited oxygen atoms.

But airglow is created by gradual solar radiation, which ionizes, or strips electrons from, gas molecules during the day. At night, these ionized molecules react with gases carrying an extra electron to regain their lost particles. These reactions release a lot of energy, which is given off as light similar to those emitted by auroras. But it causes a more gradual and often fainter light show.  related stories—Ethereal ‘halo’ and light arcs around the sun captured in photos of ultra-rare phenomena

Airglow forms 50 to 300 miles (80 to 480 kilometers) above Earth’s surface in a region of the atmosphere known as the ionosphere. At higher altitudes, airglow takes on a red color, which is produced by excited nitrogen atoms. But the green lights in the new image are a result of excited oxygen atoms and are most prominent between 56 and 62 miles (90 and 100 km) above the ground, according to Spaceweather.com.

Airglow is not the only sign from the upper atmosphere that solar maximum is fast approaching. The thermosphere, the second last layer of the atmosphere that overlaps with the ionosphere, is also warming faster than it has in almost 20 years as it soaks up energy from increasingly frequent solar storms.

Reform UK tops landmark poll for first time

Reform have topped a Sky News/YouGov poll for the first time as the party continues to shake up British politics.

Nigel Farage’s Reform UK has edged in front on 25%, with Labour pushed into second on 24% and the Tories on 21%.

The YouGov poll, taken on Sunday and Monday, also puts the Lib Dems on 14% and Greens on 9%.

Reform have overtaken Labour in the latest Sky News/YouGov poll

All the polling moves that push Reform UK to the top for the first time this week are within the margin of error and the overall picture remains unchanged – with Britain in a new period of three party politics in the polls.

However, the symbolism of Reform UK topping the poll is likely to be seized on by MPs from all parties.

Is Reform UK winning the ‘bro vote’?

The Tories are likely to be the hardest hit by the poll, having been in third place since YouGov restarted polling after the general election.

The Sky News/YouGov poll also found Kemi Badenoch has slipped behind Nigel Farage when voters are asked whether they have a favourable or unfavourable opinion of the leaders.

Last month, Badenoch has a net favourability rating of -25, but that has now dropped to -29 this month.

This puts her below Farage, who had a net favourability rating of -32 last month, which has now risen to -27 this month.

Keir Starmer is less popular than both Farage and Badenoch, with his net favourability rating now at -36.

Lib Dem leader Ed Davey is much more popular, with his net favourability rating now at -9 – although this is not directly translated across into voting intention.

These figures are likely to restart the debate in the Tory party about whether they should consider merging with Reform UK, something which Badenoch has repeatedly rejected.

A total of 43% of those polled who voted Tory in the last general election support a merger, compared with 31% against.

Reform UK voters are more likely to oppose, with 40% against and 31% for.

Starmer must delicately balance his risky EU reset as UK braces for Trump's next move on tariffs

As Donald Trump kicks off his threatened trade war by slapping tariffs on both friends and foes alike, Number 10 is preparing for the moment he turns his attention to the UK.

The unpredictability of the returning president, emboldened by a second term, means the prime minister must plan for every possible scenario.

Under normal circumstances, the special relationship might be the basis for special treatment but the early signs suggest, maybe not.

It was never going to be an easy ride, with Sir Keir Starmer’s top team racking up years of insults against Trump when they were in opposition.

The bad feeling continued when Peter Mandelson was proposed as the UK’s new ambassador to the US – prompting speculation he might even be vetoed.

Tariffs against Canada ‘will put US jobs at risk’

Amid all of this, the much-anticipated call between the two leaders seemed slow to take place, although it was cordial when POTUS finally picked up the phone last Sunday, with a trip to Washington to come “soon”.

It is against this slightly tense backdrop that the future of transatlantic trade will be decided, with Westminster braced for the impact of the president’s next move.

So, it’s unsurprising that as he waits, Sir Keir will spend the next few days resetting a different trading relationship – with Europe.

In this area, he is on slightly firmer ground, as the spectre of a global trade war makes European leaders want to huddle closer together to weather the storm.

And conversely, the Labour government’s track record works in their favour here, as they cash in their pro-EU credentials and wipe the slate clean after the bad-tempered Boris Johnson years.

It is still, however, an ambitious and risky endeavour to begin the delicate process of removing some of the most obstructive post-Brexit bureaucracy.

For minimal economic benefits on both sides, the UK must convince the Europeans that they are not letting Britain “have its cake and eat it”.

At the same time, Brexiteers back at home will cry betrayal at any hint that the UK is sneaking back into the bloc via the back door.

To make it even trickier, it must all be done with one eye on Washington, because while a united Europe may be necessary in the Trump era, the prime minister will not want to seem like he is picking sides so early on.

As with so many things in politics, it’s a delicate balancing act with the most serious of consequences, for a prime minister who is still to prove himself.

GM is cutting a shift at its EV plant in Mexico because of the Honda Prologue

GM is cutting a shift at its EV plant in Mexico because of the Honda Prologue

GM cut a shift at its Ramos Arizpe manufacturing plant in Mexico, where it builds the Chevy Equinox EV and Honda Prologue. According to GM, the move was due to Honda’s decision to slow Prologue output. With sales of its sole electric SUV in the US surging, why is Honda cutting back?

GM cuts shift at Mexico EV plant over Prologue output

Although GM just added a third shift in May 2024, the plant returned to a two-shift schedule starting on January 20.

The move was initially thought to be because its contract to build the Prologue ended, but it turns out that Honda is scaling back.

“This change is mainly due to our customer Honda’s strategy of reducing the production volume of the Prologue model,” GM said in a statement. The shift was added to meet higher export demand for gas engines and Ultium-based EVs like the Chevy Equinox and Blazer EVs and Honda’s Prologue.

With less Prologue EV output, GM no longer needs the extra shift in Mexico. According to Mexico Business News, the company is eliminating 800 jobs at the plant due to the changes.

GM also said the changes were due to “an adjustment in the mix of production of GM vehicles at the site,” so it wasn’t entirely the Prologue’s fault. The company also builds gas-powered Chevy Blazers at the site.

Honda didn’t confirm the changes, but a spokesperson (via Automotive News) said, “It is quite normal for our business to make production adjustments during the year in order to meet customer needs and market conditions. We will continue to carefully manage production and inventory for our entire product lineup to meet anticipated demand in 2025.”

After delivering the first models in March, Honda’s Prologue was one of the best-selling EVs in the US in 2024. With over 33,000 models sold last year, Honda’s electric SUV was the seventh top-selling EV, ahead of the Chevy Equinox EV (28,874).

Electrek’s Take

Given that the Prologue is one of the top-selling EVs, why is Honda slowing production? Honda is moving away from GM’s Ultium platform with its upcoming 0 Series EVs, but that isn’t the reason yet.

The Prologue was once again one of the top-selling EVs in the US last month. With 3,744 models sold, it outsold Ford’s Mustang Mach-E (3,529), the Hyundai IONIQ 5 (2,250), and the Kia EV6 (1,542).

The move to slow output at this point is questionable. As more details unfold, we’ll learn more. Check back for more information on the situation.
