Energetic solar particles are racing toward Earth, illuminating the skies as far south as Florida in a brilliant display. Meteorologists report that the intensity was powerful enough to damage several radios.
Colors of red, purple, and green adorned the skies over Alabama, Ohio, and Texas. Forecasters from the Space Weather Prediction Center indicated that the geomagnetic storm could strengthen further as the “last and most energetic CME” – a coronal mass ejection – has not yet passed and is expected to reach Earth by Wednesday afternoon.

A CME represents a spectacular event where massive clouds of protons, electrons, and magnetic fields are expelled from the Sun’s outer atmosphere at immense speeds.
Upon reaching Earth’s magnetic field, known as the magnetosphere, it interacts with particles surrounding Earth, creating vibrant auroras in the northern hemisphere and auroras australis in the southern hemisphere.

Sean Dahl, a forecaster at the NOAA Space Weather Prediction Center located in Boulder, Colorado, noted that two CMEs have already impacted Earth, resulting in a geomagnetic storm measuring a G4 on the scale of five.
The overall magnetic field strength from these CMEs is “not only eight times stronger than usual, but also conducive for continued activity right now,” Dahl explained in a video. Posted on X.
Meteorologists cautioned that this geomagnetic storm could lead to power fluctuations, degraded GPS service, and sporadic radio disruptions.

“Watches of this nature are exceedingly rare,” the Space Weather Prediction Center expressed in an advisory.
“We anticipate that the magnetic cloud, which is the ‘core’ of the current CME, is traversing Earth and will continue to do so throughout the night,” the agency declared early Wednesday.
A third, even more potent CME is expected to arrive on Wednesday, potentially allowing the aurora borealis to be visible further south.
Dahl mentioned that the second-highest level advisory would remain valid for several more hours, with a possibility of reaching the highest rating, G5.

On Monday, air quality warnings were issued for millions across the upper Midwest and northeastern regions as smoke from wildfires in Canada moved into these areas.
Areas expected to experience hazy skies include Minnesota, Wisconsin, Michigan, Northern Indiana, Pennsylvania, New York, New Jersey, Connecticut, Massachusetts, Vermont, Rhode Island, New Hampshire, Delaware, and Maine. The National Weather Service reports.
In Canada, approximately 200 wildfires remain uncontrolled, including 81 in Saskatchewan, 159 in Manitoba, and 61 in Ontario. Data from Canada’s Interagency Forest Fire Centre indicates that over 16.5 million acres have been affected this year, which may lead to a record-breaking wildfire season.
The Air Quality Index on Monday across 14 Midwest and Northeastern states indicated conditions ranging from “moderate” to “unhealthy” for the general population.
Wildfire smoke is particularly hazardous as it contains fine particles measuring less than 2.5 micrometers in diameter, which is about 4% the width of an average human hair. This type of pollution can penetrate deeply into the lungs, exacerbating asthma, lung cancer, and other chronic respiratory conditions.
High levels of air pollution can lead to inflammation and weaken the immune system. Infants, children, the elderly, and pregnant women are especially at risk during poor air quality conditions.
Research indicates that climate change contributes to the frequency and intensity of wildfires. Elevated temperatures can desiccate vegetation, elevating the likelihood of wildfires igniting and spreading quickly.
Cities experiencing poor air quality on Monday included Milwaukee, Detroit, Buffalo, Albany (New York), Boston, and New York City. Multiple alerts are in effect until Tuesday, as reported by the Weather Bureau.
In the western regions, several wildfires are causing additional air quality concerns. Over 65,000 acres have burned in California’s Los Padres National Forest, where high temperatures and dry conditions are fueling the growth of wildfires.
In Colorado, the Air Quality Index also displayed “moderate” readings on Monday.
“If the smoke becomes thick in your area, we advise you to remain indoors,” stated the Colorado Department of Public Health and Environment. This recommendation particularly applies to individuals with heart diseases, respiratory issues, young children, and the elderly. If smoke levels are moderate to intense, consider reducing outdoor activities.
Superb Starling (Lamprotornis superbus) Recent studies reveal their behavior of “reciprocity,” where they assist each other with the expectation of future favors.

The Superb Starling is a passerine bird belonging to the Sturnidae family.
This species is widespread, inhabiting various regions in East Africa, including Ethiopia, Somalia, Uganda, Kenya, South Sudan, Tanzania, and beyond.
These birds form large mixed groups consisting of 7 to 60 individuals, with an average size ranging from 13 to 41 members.
“The social structure of Starlings is complex, comprising not only family units but also a mix of both related and unrelated individuals, much like humans.”
“It’s well-known that animals tend to assist their relatives to enhance genetic fitness and propagate their genes.”
“While Starlings prioritize helping relatives, they also lend support to unrelated individuals.”
Professor Rubenstein and his team discovered that this support arises through the establishment of mutual relationships.
However, proving that such behaviors are present in non-relatives remains challenging.
The study is rooted in two decades of research by the authors on these birds in Africa, thriving in the harsh savannah climate.
From 2002 to 2021, thousands of interactions among hundreds of birds were documented, alongside DNA samples to analyse genetic links.
By merging behavioral data with genetic information during 40 breeding seasons, they posed pivotal questions: Did birds prioritize aiding relatives? Did they assist non-relatives when related individuals were available? Did they reciprocate support over time?
Ultimately, the findings revealed that while helpers prioritized their relatives, they often supported specific unrelated individuals consistently, even when relatives could assist.
“Many of these birds forge friendships that develop over time,” Professor Rubenstein stated.
“Our next goal is to investigate how these relationships are formed, their longevity, and why some bonds remain strong while others diminish.”
The study was published today in the journal Nature.

Robots that can take off like birds could eliminate the need for runways for small fixed-wing drones.
Birds use the powerful explosive force generated by their legs to jump into the sky and begin flight, but it has proven difficult to build robots that can withstand the strong accelerations and forces exerted during this process.
now, Won Dong Shin Researchers at the Swiss Federal Institute of Technology Lausanne (EPFL) have developed a flying propeller robot called RAVEN. The robot has legs that move like a bird and can walk, hop, jump into the air and start flying.
“Fixed-wing aircraft like airplanes always need a runway or a launcher, but that's not available everywhere. You really need a designated infrastructure to get the plane off the ground,” Singh said. Masu. “But when they spot a bird, they just walk around, jump, take off. It's very easy for them. They don't need any outside help.”
A real bird's legs have joints at the hip, knee, and ankle, but RAVEN's legs have only two joints, the hip and knee, and are driven by a motor. Each leg also has a spring that can store and release elastic energy. By using fewer parts, Singh and his team were able to keep RAVEN's weight to about 600 grams, the same as a crow.
In indoor tests, RAVEN was able to jump approximately 0.5 meters into the air at a speed of 2.4 meters per second. This is a similar speed to birds of the same size. At this point the propeller takes over. Because it can be launched upwards from anywhere, RAVEN could be useful for disaster relief missions where regular fixed-wing drones cannot take off or land, Singh said. But first, he says, the team needs to develop RAVEN's ability to land safely.
“We've seen a lot of work on flying robots that land on perches, but not many focused on taking off with their feet,” he says. Rafael ZafriEPFL was also not involved in this work. “I think the two disciplines of landing, or perching, and takeoff will be integrated into one platform that will allow robots to fly, detect branches, land, recover, and perform missions.” Take off. ”
ohOn September 1, 1974, two men made the fastest trip ever between New York and London. Traveling three times the speed of sound and taking less than two hours, this incredible journey set a record that still stands 50 years later.
Even the mighty Concorde, which set the record for the fastest commercial transatlantic flight in 1996, was almost an hour late.
The US Air Force Lockheed Blackbird SR-71 jet, with a crew of two – pilot James Sullivan and reconnaissance systems operator Noel Widdifield – completed the flight between the two cities in one hour, 54 minutes and 56 seconds, before landing in triumph to a great welcome at the Farnborough Air Show in Hampshire.
Widdifield, now 83, divides his time between Virginia and Florida in the US. “In some ways it was a normal flight for us,” he said, reflecting on that momentous day. “There was nothing unusual about the flight or the way we flew the plane, but in July 1974 we were told we were going to attempt the world record for flying from New York to London, which had previously been held by a Royal Navy pilot. There was a lot of media interest.”
It wasn’t just the Air Force’s prestige that was at stake. America was facing an international public relations crisis. Just three weeks earlier, disgraced President Richard Nixon had resigned after the Watergate scandal and Gerald Ford had taken over the White House. The country was still reeling from its disastrous involvement in the Vietnam War. The country needed something to cheer about.
There were other schemes as well. Widdifield observer“Although I didn’t know anything about it at the time, behind the scenes, negotiations were taking place between the US and the UK to deploy Blackbird SR-71s on British soil.

“There were fears in the UK that this move might cause a lot of backlash, especially in the Middle East. But after we broke the record and flew into the Farnborough Air Show, that seemed to be the clincher and the UK allowed the SR-71 to be parked.”
Widdifield was 33 when he made this historic flight. He originally wanted to be a train driver, but after seeing U.S. Air Force jets flying low over his house at age 12, he decided to become a pilot.
After training and flying B-52 bombers, Widdifield served in the Blackbird SR-71 program at Beale Air Force Base in California from 1971 to 1975, after which he retired from flying to serve in the U.S. space program until 1982.
Piloting a Blackbird was akin to being an astronaut: The crew wore space suits and flew at an altitude of 80,000 feet (most commercial airliners top out at 42,000 feet). “It was pitch black up there,” Widdifield said. “You could see the stars and, depending on the time of day, the moon or the sun.”
Their plane took off from Beale and had to fly along the coast to New York to avoid creating a sonic boom over populated areas and causing significant damage to buildings. High above the city was an invisible “gate” where the journey would begin. Reaching a speed of Mach 3.2 (three times the speed of sound, about 2,455 miles per hour), the Blackbird crashed through the gate and the record attempt began.
The plane had to refuel twice: once upon takeoff, once when it docked with a tanker over California to top off, and once en route to near Greenland.
In one incident that looked terrifying from the outside but was handled with cool by the crew, the Blackbird suddenly began to “yaw,” or move quickly from side to side, after losing thrust.
Because the Blackbird took in air from the front to provide thrust for the engines, the air intake mechanisms would often become misaligned, causing a momentary, significant loss of power in one engine.

“The automatic restart system was activated, the misaligned cones were corrected and the engine was restarted,” Widdifield said. “We had no real concerns other than what this would do to our record speed run.”
The plane then flew through the London “gates” without incident, and the Blackbird landed at Farnborough, where a large crowd waited and a press conference was held, during which Widdifield and Sullivan were on the phone with the new president. “It got huge international coverage for the next year,” says Widdifield, who has six scrapbooks of the clippings. “But what Jim and I always tried to emphasize was that although it was just the two of us who got the glory, there was a huge team behind every flight.
“When you take into account the support staff, the administrative staff and all the people who work to get us flying, that’s 1,000 people. They deserve as much credit as Jim and I do.”
Widdifield, who has been married to his wife Ann for 63 years and has two children, five grandchildren, and two great-grandchildren, is mourning the loss of his co-pilot, Jim Sullivan, who died in 2021, and the Blackbird SR-71 itself, which was officially retired in 1998.
He said: “Jim and I kept in touch but then lived far apart so we only saw each other a few times at SR-71 reunions.
“Obviously I was sad when the SR-71 program ended. So am I surprised that no one has beaten our record in 50 years? No, because no aircraft has been built since then that could break that record.”

Increased solar activity has led to widespread aurora borealis across Canada.
A surge in solar activity in mid-December 2023 caused energetic particles to collide with Earth’s magnetosphere, creating rippling auroras across Earth’s northern latitudes. VIIRS (Visible Infrared Imaging Radiometer Suite) NOAA– NASA
The Suomi NPP satellite captured this image of light from the aurora borealis over western Canada in the early morning hours of December 17, 2023. VIIRS’s day/night band detects nighttime light at wavelengths ranging from green to near-infrared, using filtering techniques to observe signals such as city lights, moonlight reflections, and the aurora borealis.
Origin of the aurora borealis
These auroras may have resulted from several coronal mass ejections. observed December 14th and 15th.mild to moderate Magnetic storm situation Weather forecasts were expected within days, according to NOAA’s Space Weather Prediction Center. coronal mass ejection contains large amounts of plasma It is emitted from the sun’s corona and carries an embedded magnetic field.Interactions between these emissions from the Sun and Earth’s upper atmosphere produce light Produces a colorful aurora.
Increased solar activity
Solar activity is increasing as we approach the peak of solar cycle 25, which is predicted to occur on or around the year 25. July 2025. The Sun’s magnetic field reverses at the peak of these cycles, and each cycle lasts about 11 years. Scientists track fluctuations in solar activity by monitoring the number and location of sunspots, the dark spots on the sun’s surface that are the main cause of solar eruptions.
Relationship between aurora and solar flares
The aurora seen here occurred several days after the aurora borealis. strongest solar flare How has this solar cycle been so far? While coronal mass ejections take days to reach Earth, solar flares can reach Earth in minutes and disrupt radio communications. Coronal mass ejections often, but not always, occur in parallel with solar flares.

Rocket LabHis Electron rocket will likely return to flight by the end of the year, but the work is not yet complete before the mission resumes, according to a new statement released Wednesday.
Rocket Lab announced it has received permission from the Federal Aviation Administration to resume Electron launches from its New Zealand launch facility, but that doesn’t mean regulators have given the green light. Rocket Lab must complete an investigation into the anomaly that led to the Sept. 19 mission failure and implement an FAA-approved accident investigation plan to ensure the problem is resolved.
“Rocket Lab is currently in the final stages of a thorough investigation into the root cause of the anomaly. This process includes examining an extensive fault tree to cover all potential causes of the anomaly and This includes completing a comprehensive test campaign for reproduction on the ground,” the company said in a statement.
Standard practice after a rocket launch failure is for a company-led accident investigation to be conducted under the supervision and approval of the FAA. Rocket Lab said a full review is expected to be completed “in the coming weeks.”
Rocket Lab has not said anything about the cause of the September failure that led to the loss of Capella Space’s synthetic aperture radar satellite. The problem occurred shortly after the second stage’s single-engine Rutherford engine ignited, approximately two and a half minutes after liftoff. Rocket Lab CEO Peter Beck said in a statement that given Electron’s flight history, “a failure would be a complex and extremely rare problem that has never occurred in any previous test or flight.” He just said he knew.
An anomaly occurred during Rocket Lab 41.cent Electron firing. Before the anomaly, the company had completed 20 consecutive orbital launches.
