    However, after further analysis, NOAA's Space Weather Prediction Center issued a Moderate (G2) geomagnetic storm watch for July 3, indicating that at least part of the CME could land Earth with a significant blow.

  4. My estimation (based on the position of #AR4366) is that it will be Earth-facing in 4-5 days...

    "Sunspot Watch
    January 31, 2026 @ 04:15 UTC
    Newly assigned sunspot region 4366 continues to gradually develop as it turns into view in the northeast quadrant. It is currently producing minor C-Class flares and it is likely now a threat for a moderate M-Flare. Something to keep an eye on this weekend. Image by SDO/HMI.

    Growing Flare Threat
    January 31, 2026 @ 14:50 UTC
    AR 4366 continued to expand over the past 12 hours in both size and magnetic complexity. The region has a Beta-Delta magnetic configuration and is producing frequent mid level minor C-Flares. A moderate M-Flare will remain possible on Saturday.

    M6.6 Solar Flare
    February 1, 2026 @ 10:40 UTC
    Solar activity increases even further with an M6.6 solar flare peaking at 10:02 UTC (Feb 1). The source, AR 4366, is magnetically complex and is now a threat for an isolated X-Flare. Image below by SDO/AIA.

    High Solar Activity
    February 1, 2026 @ 16:50 UTC (UPDATED)
    What a difference a few days make on the Sun. Active sunspot region 4366 turned into a firecracker on Sunday with at least fifteen M-Class solar flares and one X-Flare (so far). Despite the brightness of these events, the mechanics have so far failed to launch any noteworthy coronal mass ejections into space and towards our planet. That could change over the next few days as the region continues to develop and currently sports a Beta-Gamma-Delta magnetic configuration. More solar flares including another X-Flare will remain possible.

    [And today...]

    Impulsive X8.1 Solar Flare
    February 2, 2026 @ 00:10 UTC
    An impulsive X8.1 solar flare was just detected peaking at 23:57 UTC (Feb 1). This is the second strongest flare in terms of peak X-Ray flux of the current solar cycle. Although a bright flare, new imagery suggests that if a CME is associated, it will likely be fairly mild. Stay tuned to SolarHam where you will get the most up to date and accurate information regarding this space weather event."

  6. It's like #ElonMusk wants there to be a #KesslerEffect! Hard to launch a space program if we can't leave Earth!

    #SpaceX seeks go-ahead from the #FCC to put up to a million #DataCenter satellites in orbit

    by Alan Boyle on Jan 31, 2026

    Excerpt: "SpaceX founder Elon Musk wasn’t kidding about his plans to go big with orbital data centers: The company is asking the Federal Communications Commission to approve a plan to put up to a million satellites in orbit to process data for artificial intelligence applications.

    " 'Launching a constellation of a million satellites that operate as orbital data centers is a first step towards becoming a #Kardashev II-level civilization — one that can harness the sun’s full power — while supporting #AI-driven applications for billions of people today and ensuring humanity’s #multiplanetary future amongst the stars,' SpaceX said in an application filed with the FCC on Friday."

    'The sun is slowly waking up': NASA warns that there may be more extreme #SpaceWeather for decades to come
    News

    A new NASA study suggests that solar activity will remain high or rise further in the coming decades, contradicting previous assumptions that the sun was quieting down — and scientists "don't completely understand" why.

    By Harry Baker, published September 17, 2025

    "NASA scientists are warning that the sun may be "waking up" from a brief period of relative inactivity, contradicting past assumptions about our home star. If true, this could mean that decades of potentially dangerous space weather are in store.

    [...]

    "In a new study, published Sept. 8 in The Astrophysical Journal Letters, researchers analyzed multiple metrics of solar activity, including solar wind, magnetic field strength and sunspot numbers, and found that they have been on an upward trend since around 2008, and could rise further over future cycles, suggesting that the deep solar minimum theory is well and truly dead.

    [...]

    "During the current maximum, Earth has also been hit by several major geomagnetic storms, or disturbances to the planet's magnetic field. The most noteworthy was an 'extreme' event in May 2024, which triggered some of the most vibrant aurora displays in centuries and caused over $500 million in damages."

  10. @QuadRadical So, basically, if you are able to call your phone in whatever you're using as a #FaradayCage, it's NOT going to be effective against #EMPs.

    "Trefethen also points out that microwave ovens, despite their thick wires, are not perfect Faraday cages. That is because if you put your mobile phone – which communicates via microwaves – into an oven and call it, it will almost certainly ring."

  20. @QuadRadical Hmmmm... That may not work... I'd say maybe wrapping stuff up in aluminum foil might provide more protection. Wrapping them in foil and put them in the microwave *might* work.

    "A microwave is an electric oven that heats and cooks food by exposing it to microwave-frequency electromagnetic radiation. People use this to heat their foods quickly, and some are curious if microwaves can classify as an example of Faraday cages.

    "This article will show you what a faraday cage is and if a microwave is considered a faraday cage.

    Is a Microwave a #FaradayCage?

    "Simply put, Faraday Cages disperse electrostatic charge around their perimeter. As a result, they act as a barrier to anything within them.

    "In this regard, they are a hollow conductor in which the electromagnetic charge remains only on the cage’s external surface. But, as with many things, the reality is a little more complicated.

    "Microwave ovens are another common application for Faraday Cages. However, unlike other applications, they are designed to reverse and keep the microwave radiation within the oven. You can see a portion of the cage on the microwave oven’s transparent window.

    "Microwaves nowadays are not built and designed as a Faraday cage, but rather a 1/4 wave choke that effectively attenuates 2.4 GHz but not other frequencies.

    However,

    "A Faraday cage is from any material that conducts electricity. This cage could be wire mesh, metallic sheets, or wire coils. They can be any shape, such as a box, sphere, or cylinder, and any size, ranging from extremely small to extremely large.

    "According to Florida State University, the cage’s exterior can be as simple as aluminum foil. The outer covering, or conductor, can be as thin as foil, but thickening it will provide additional protection from more powerful electric fields."

  25. I'm not sure what's going to happen, but I plan on making sure all my electronics are turned off and disconnected, and might put some of them in a makeshift #FaradayCage until after the #CMEs hit Earth. I'd like to think utilities and such will have learned from warnings from 2013, but then again, it's the human race we're talking about. Unless there's a buck to be made, we seem to be woefully unprepared for stuff that can happen -- unfortunately...

    "If a massive CME were spotted, such 3-day forecasts give us some lead time: there are some measures #ElectricUtilities could take to protect their equipment, such as quickly disconnecting #transformers. Polar flights, which travel at the highest altitudes, could be rerouted to avoid contact with damaging solar particles, and some #satellites could be switched into a #SafeMode to minimize damage.
