  1. 🌞 A Plan to Stop Solar Storms From Sending Us Back to the Stone Age

    「 Far out in space, where geostationary satellites orbit, a half-dozen school-bus-size satellites crack open and start dumping barium, lithium or sodium. Within minutes, sunlight transforms this material into an ionized gas shield that slows the oncoming massive blob of plasma 」

  3. Extreme dominance of Earth-origin heavy ions in the intense #RingCurrent near the Earth during the May 2024 super #GeomagneticStorm: science.org/doi/10.1126/sciadv -> Earth’s #ionosphere supplied vast majority of ring current ions during May 2024 super geomagnetic storm, study finds: en.nagoya-u.ac.jp/news/article - despite the dense solar wind, solar wind ion contributions to the ring current during the May 2024 superstorm were minimal; the first simultaneous observation of ring current ions and solar wind during a storm this large.

  9. Getting ready for the next #CarringtonEvent. :-)

    "The May 2024 geomagnetic storm was the largest for over 20 years. The storm was categorized as a ‘low-level’ G5, where G5 is the highest on the National Oceanic and Atmospheric Administration (NOAA) scale for geomagnetic storms, yet the individual solar eruptive events were not particularly severe, and the observed impacts were relatively minor. The impacts that were observed were due to the combined and sustained effect of five successive earthward-directed coronal mass ejections (CMEs) which drove the storm. The event exposed the weakness of the current storm classification system which does not discriminate between low impact and high impact G5 events; it exercised the UK Met Office forecasting system, communications and UK preparedness; and it highlighted key areas that need to be addressed, particularly relating to national power supplies, space traffic management, aviation, forecasting and data gaps. Here, we set out what happened, record some of the key impacts, discuss what went well and what needs to be improved. We make 14 recommendations relevant to four government departments, so that the UK can be better prepared for a low-probability, high-impact space weather event described in the reasonable worst-case scenario that informs the national risk register."

  13. New preprint!

    We reviewed global catastrophic risks: nuclear war, volcanic eruptions, asteroid impacts, cyberattacks, EMP, geomagnetic storms, and pandemics. Which places on Earth are most resilient?

    The short answer: nowhere is safe from everything. Australia and New Zealand come closest, but even they have serious vulnerabilities (trade dependence or volcanic exposure).

    The key finding is that resilience factors actively trade off against each other. Geographic isolation helps in pandemics but hurts during infrastructure collapse. A large industrial base helps produce emergency food but increases digital vulnerability.

    What could help across scenarios: democratic governance, low inequality, decentralized systems, food self-sufficiency, and preparation. Most of these are policy choices, not geographic fate.

    You can find the whole preprint here: eartharxiv.org/repository/view

  17. Northern Lights Over North Cork

  19. Northern Lights Over North Cork

    You don’t expect to stand in a field north of Blarney and watch the northern lights, but here we are. Last night the aurora put on a show visible well into southern Ireland. Bands of pink and magenta hung across the sky, bleeding into that unmistakable green glow along the horizon. To the naked eye nothing could be seen, but the camera pulled out colours that made the whole scene look otherworldly.

    A passing car lit up the bare trees on the ridge at just the right moment, backlighting them with a warm glow that played off the green aurora behind. It was one of those happy accidents you couldn’t plan if you tried. Even the electricity poles added something, a reminder that this was a country road in Cork, not the Arctic Circle. These events have become more frequent as we near solar maximum, so keep an eye on the Kp index and have a dark-sky spot in mind, because the next one might be even better.

  23. 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.
