    Low-Earth orbit is a 'house of cards' that is just 2.8 days from a catastrophic collision
    "
    ".. the system is getting so crowded, so maneuver-dependent, and so reliant on constant control that a rare disruption – especially a strong solar storm – could push it from “busy but manageable” to “we can’t keep up” surprisingly fast."

  4. Could a powerful geomagnetic storm be the reason 8,000 Victorian homes suddenly lost power in January this year?

    I had a chat with Dr Richard Marshall from Australian Bureau of Meteorology Space Weather about the origin of solar storms and the risks they present to our communities and critical infrastructure.

    So great to be able to have such fantastic and professional insights about these important events and how we, as a society, need to mitigate against them.

  6. Y’all. Take just a moment to forget everything humanity has ever done, and watch the amazing G5 geomagnetic storm as it rips through our fragile air bubble.

    That our puny race of hairless apes has survived aeons despite everything the universe throws at us, well surely it’s a mathematical improbability. Well done everybody! Take the 23rd off.

    "Transpower has issued a grid emergency notice ahead of a severe geomagnetic storm and removed some South Island electricity transmission lines from service.

    The national grid operator says the move won't affect the electricity supply to homes and businesses, but will prevent damage to critical equipment if the storm worsens.

    Geomagnetic storms can send unwanted currents through electricity circuits, and have the potential to cause serious damage if they reach substations transformers or large hydroelectric dams.

    The storms are caused by space weather, when the Sun ejects plasma and other matter in Earth's direction.

    Coronal mass ejections (CME) are rare, and generally aren't noticed on earth thanks to the planet's magnetic field shielding the planet from particles, Transpower said."

  16. Aurora Australis from Royal National Park! This is AMAZING.

    The big solar storm that is passing us this week, triggered nu a coronal mass ejection from the Sun has produced a class G4 / G5 geomagnetic storm.

    Our magnetosphere deflects most of the particles from Sun away, but near the poles, some spiral down and excite our atmosphere - producing aurora.

    This storm was powerful enough to generate aurora sightings as far north as Coonabarabran and the Siding Spring Observatory. That's around 340 km NW of Sydney (closer to the equator, at 31 degrees south!)

    While city lights drowned out the view for many, those under darker skies were treated to an extraordinary show. This stunning timelapse footage, captured by my friend Filippo Rivetti from Royal National Park south of Sydney, offers a glimpse of the awe-inspiring beauty and planetary-scale force of this event.

    A reminder of the vast, dynamic forces at play: a star lashing out across space, and a planet, our home planet with its protective magnetic shield - hosting the only life we know of so far in the Universe, safely within.

  17. FEMA Briefing on the G4 (Severe) Geomagnetic Storm

    "Situation: The Space Weather Prediction Center (SWPC) issued an Alert at 4:00 a.m. ET, for a G4 (Severe) Geomagnetic Storm or greater. The Alert is in effect through Monday,
    June 2, and the primary area of impact lies poleward of 50 degrees North Geomagnetic Latitude. While some critical infrastructure may be negatively impacted, key operators can
    mitigate these impacts. The United States Department of Energy, Cybersecurity and Infrastructure Security Agency (CISA) Central, and the United States Department of
    Transportation (DOT) have been contacted and continue to monitor with nothing significant to report at this time"

  19. The #Carrington Event was both the most powerful #SolarStorm and the most powerful #Geomagnetic #Storm ever recorded.

    It started with an incredibly intense solar flare, the most powerful ever observed, releasing a massive amount of energy and matter from the Sun.

    This solar storm sent a massive coronal mass ejection towards Earth, which then slammed into our magnetosphere, causing the most intense geomagnetic storm ever recorded.

  26. [May be behind a paywall] The Strongest #SolarStorm in 20 Years Did Little Damage, but Worse #SpaceWeather Is Coming

    Years of careful planning helped safeguard against last weekend’s severe space weather, but we still don’t know how we’d cope with a monster event

    By Jonathan O'Callaghan & Lee Billings
    May 16, 2024

    "For years, we have been warned about impending doom from the sun. If pointed in our direction, powerful eruptions of radiation and plasma from our star can strike our planet to supercharge Earth’s atmosphere and magnetic field, effectively hitting a global 'reset' button on much of our #ModernTechnology. A sufficiently intense bombardment could raise a #Geomagneticstorm that would push satellites out of orbit, short out submarine cables that suture together the #Internet and plunge the world into darkness with massive #blackouts from collapsed #PowerGrids. Yet this past weekend, when one of the strongest solar outbursts in 20 years blasted our planet, we managed to emerge unscathed thanks to years of careful public and private planning.

    "The storm has ebbed, although the solar region that sparked it has since spat out additional monstrous flares—fortunately no longer targeted at Earth because of the sun’s spin [which will change in a short time, as that spot will once again be Earth-facing]. But while we’ve passed our biggest test yet, experts say now is not the time to let down our guard: the question of more cataclysmic solar activity isn’t a matter of 'if' but 'when.'

    "'This is a success story,' says Shawn Dahl, a space weather forecaster at the National Oceanic and Atmospheric Administration’s [#NOAA] Space Weather Prediction Center (#SWPC) in Boulder, Colo., but the weekend’s storm was 'nowhere close' to the strength of more powerful known historical events. Is it time to put our feet up? 'Heck no,' he says.

    "On May 8, after ground- and space-based telescopes detected multiple explosive outbursts from the sun headed for Earth, the SWPC issued a warning of an imminent severe space weather event. At least seven of these outbursts, known as coronal mass ejections, or #CMEs, walloped our planet with billions of tons of solar plasma—an interplanetary punch that left Earth’s magnetic field ringing and made the upper atmosphere swell, almost as if bruised. The resulting geomagnetic storm was the most severe since 2003. It posed potentially grave dangers to global infrastructure while also bathing much of the world in achingly beautiful #auroral displays.

    "At present, it’s difficult to say just how close we came to catastrophe because many companies— from grid controllers to satellite operators—do not like to reveal information on how a geomagnetic storm affected them, says Daniel Welling, a climate and space scientist at the University of Michigan. "'They don’t want to look like they’re vulnerable,' he says. 'Satellite operators have to insure their spacecraft, and that can be very expensive.' Yet various scattered reports are already offering some insight into the storm’s disruptive effects. Flight trackers showed airlines rerouting planes to avoid Earth’s poles, where crews and passengers would have been exposed to worrisome spikes in #CosmicRadiation from the storm. Transpower, New Zealand’s state-owned enterprise running that nation’s electric power, said in a statement that it had preemptively 'switched off some circuits across the country on Saturday [May 11],' and as a result, there was 'no impact on New Zealand’s electricity supply.' In Minnesota, the firm Minnesota Power opened capacitor banks to deal with possible effects from the storm. Similar precautions were likely taken at other power grids around the world, too, although the lack of information makes it 'tremendously' difficult to know how effective those measures were, Welling says.

    "Geomagnetic storms can also play havoc with signals from #GPS satellites, and multiple farmers reported issues with GPS-guided farming equipment over the weekend. In South Dakota, one farmer’s tractor started #DrivingInCircles during the storm, and multiple farmers reported outages on social media. 'Our GPS on both the planter and the strip tiller were absolutely bonkers today,' one commenter wrote on Reddit. 'I saw this post and looked ... no GPS,' said another. LandMark Implement, a John Deere dealership based in Nebraska and Kansas, texted its customers an advisory to 'turn off' GPS devices on their farming equipment. 'The base stations were sending out corrections that have been affected by the geomagnetic storm and were causing drastic shifts in the field,' the company noted in an online post. LandMark declined to comment further when contacted.

    "The storm posed hazards in space as well. Seven astronauts on the International Space Station were mostly safe from the storm’s effects, #NASA said, but did have to take some precautions. 'The crew was told to avoid lower-shielded areas of the space station out of an abundance of caution,' says Sandra Jones, a spokesperson for NASA’s Johnson Space Center. 'Certain areas provide less protection from radiation, such as the air lock, while other areas, such as crew quarters, provide enhanced protection. The crew was never in any danger, and the energy levels have since decreased.' Other satellite operators experienced greater difficulties. One company in the U.K., Sen, which streams 4K video from a satellite in low-Earth orbit, chose to power down its spacecraft for four days to prevent any damage from the storm, such as fried circuit boards or electronic failures. 'It was in an idle mode,' says Marcin Bujar, spacecraft operations lead at Sen. 'We just kept the bare minimum on—the flight computer and radio receiver.' This prevented the satellite from carrying out some tasks, including planned observations of flooding in South America and wildfires in Canada. 'It definitely had an impact,' Bujar says."

  28. Bueno, en el Sol acaba de ocurrir una erupción solar clase X8.7 hace apenas un rato, siguiendo otras dos flares clase X1.7 y X1.2, la alerta por correo de esta última no ha llegado aún. Estos eventos fueron detectados por el radiotelescopio e-callisto del OALM y han ocasionado un type II y type III radio burst que son básicamente, señales de radio intensas, generadas por la aceleración por onda de choque de los electrones en la corona solar, que muchas veces acompañan las eyecciones de masa coronal o CMEs . El proyecto e-Callisto es una red internacional de estaciones terrenas con radiotelescopios de bajo costo que observan la actividad solar las 24hs distribuidos por todas partes del mundo entre 45 y 870MHz y que buscan detectar estos bursts o explosiones en radio. Esto ayuda a caracterizar la la actividad solar y en casos de eyecciónes de masa coronal, ayudar a determinar la velocidad de las partículas que vienen hacia la Tierra.
