    I was reading it could get as high as a 3 or a 4 where people across the middle of US might even see the Aurora Borealis.
    Being in MI it could be a spectacular display at my QTH.
    Nice to see the Sun coming back to life and bringing decent band conditions with it. I'm already prepared incase she gets a little too rowdy. I keep backup rigs in a file cabinet and a 1965 Kaiser Willy's CJ5 with the GM Dauntless V6, points ignition, locked Dana 44's and plenty of fuel.

    There will probably be an HF blackout later today. But as to risks to equipment, No.

    The earth gets hit with CMEs fairly frequently. This is not of the magnitude to cause damage. What it means is that the Sun is coming back to life as we climb out of the sunspot pit we've been stuck in the past couple years!

    All of what you're seeing in the thread about wrapping things in foil, ammo cans, and so on, is just sarcasm and banter.

    Information and news here:

    (on the other hand, if you're prone to conspiracy theories, maybe I'm just saying that so you'll let your guard down... ;))

    Well that’s just great... I went to 15 different stores and there’s been a run on aluminum foil and ammo cans! There’s none to be had now!!!

    Solar flares degrade toilet paper, so you’d also better pick up more of that before it’s all gone. :D

    I found this on

    The explosion also hurled a coronal mass ejection (CME) toward Earth. Coronagraph images from the Solar and Heliospheric Observatory (SOHO) show a halo CME leaving the sun a few hours after the flare:

    NOAA analysts have modeled the storm cloud; their results confirm that it will likely reach Earth during the second half of Dec. 9th. En route to our planet, the CME will scoop up some slower-moving material from an unrelated solar wind stream. The combined impact could spark geomagnetic storms as strong as category G3, although lesser G1- to G2-class storms are more likely.

    This is NOT a major space weather event. But after 3 years of uber-quiet Solar Minimum, it is noteworthy. If a strong geomagnetic storm materializes, auroras could be sighted in northern-tier US states from Maine to Montana to Washington.

    No reason to worry much even if the polarity is south it won't be that bad. Just some usual disruptions. Yes the magnetic field is weak but still there. should be good for HF though and that's fine.

    As others replied, no risks to electronics, could be mild HF blackout...

    And perhaps a little enhancement (and noise), later, after things settle down. Listen around the bands tomorrow, Thursday.

    Try running WSPR today and tomorrow, and check your RX map every few hours. Should be interesting.

    I accidentally sent the wrong graph - sorry for the inconvenience. This is the correct one.
    First storm was picked up by the RF-Seismograph from 19:00 UTC to 06:00 UTC on 80 m, on 40 m, and on 20 m from 23:00 UTC to 06:00UTC.
    Also mot the noise increase on 15 m between 03:00 UTC and 07:00 UTC.
