    Major X2.3 solar flare / Geomagnetic storm

    "GEOMAGNETIC STORM WATCH (UPDATED): Photographers, warm up your cameras. A CME is heading for Earth, and it could spark a good display of auroras when it arrives later today or tomorrow. NASA's computer model of the CME suggests it will reach Earth on Feb. 17th at 1800 UT. (Update: This time has passed with no CME yet.) First contact is expected to produce a minor G1-class geomagnetic storm, intensifying to moderate G2-class storming on Feb. 18th. During such storms, auroras can spill into the United States as far south as New York and Idaho".

    https://spaceweather.com/


    "A Major long duration X2.3 solar flare was just observed at 20:16 UTC Feb 17 from newly assigned Active Region 13229. Associated with this blast was a R3 Radio Blackout with a strong Coronal Mass Ejection(CME) exiting the solar corona but will not have an earth bound component. Also a Type III radio emission with an estimated velocity of 2400 km/s was recorded".

    It's a matter of time before we get hit by a major EMP type disturbance. We know they happen, just not that often and not directed at us on this little planet..................

    Check out this beautiful filament eruption.




    "A "CHAIN REACTION" EXPLOSION ON THE SUN: A magnetic filament connected to sunspot AR3229 erupted on Feb. 24th, producing a chain reaction of events that could lead to a geomagnetic storm on Earth. The action began at 1949 UTC when the filament rose up and sliced through the sun's atmosphere".

    A CME occurs about every 4 days. None are "directed" at us.

    Major X2 Solar Flare with CME

    We had another X flare today it is not directly earth facing. There was a CME, we may or may not recieve a glancing blow.

    "A strong X2.07 solar flare (R3 level radio blackout) was just observed around AR 3234 peaking at 17:52 UTC (Mar 3). A further update will be provided should a coronal mass ejection (CME) be associated. Because of the location towards the NW limb, any eruption around this region would not be squarely directed towards our planet. More to follow.

    CME UPDATE: A coronal mass ejection (CME) is seen emerging following the X2 solar flare around AR 3234 today. A expected, it is heading to the west. Only a glancing blow at best could be expected within 72 hours, however it should mostly be a miss".

    "ANOTHER X-CLASS SOLAR FLARE: Earth-orbiting satellites have just detected an X2-class solar flare (1752 UTC). The source is departing sunspot AR3234. NASA's Solar Dynamics Observatory recorded the extreme ultraviolet flash".

    "Radiation from the flare ionized the top of Earth's atmosphere, causing a shortwave radio blackout over the Americas: map. Aviators and ham radio operators may have noticed loss of signal and other unusual propagation effects at frequencies below 30 MHz for as much as an hour after the flare".

    Check out these magnificent aurora from the recent G3 solar storm. This was from Feb 26th to 28th. Awesome vid. https://twitter.com/NightLights_AM/s...51094713409542

    'extremely rare' farside cme'

    “Something big just happened on the farside of the sun. During the early hours of March 13th, SOHO coronagraphs recorded a farside halo CME apparently leaving the sun faster than 3000 km/s:

    Because of its extreme speed, this CME may be classified as "extremely rare," a fast-mover that occurs only once every decade or so. A NASA model of the event shows the CME heading almost directly away from Earth. Good thing!

    Although the CME is not Earth-directed, it has nevertheless touched our planet. See all the snowy dots and streaks in the coronagraph movie above? Those are energetic particles accelerated by shock waves in the CME. They create short-lived luminous speckles when they hit SOHO's digital camera.

    NOAA's GOES-16 satellite has detected the particles reaching Earth--all from the CME's backside. Imagine what a frontside blast would have been like! Earth's magnetic field is funneling the particles toward the poles where a type of radio blackout is underway--a polar cap absorption (PCA) event”. https://spaceweather.com/

    Hopefully the one day the big one hits earth is like a hundred thousand years in the future.

    The sun is getting more active than it has for a decade — and it could lead to power outages, grounded flights, and stunning auroras

    • The sun is entering a period of peak activity that will last several years, an expert said.
    • This means the sun will produce more solar flares, powerful bursts of energy.
    • Solar flares can disrupt radio communications and electric power grids on Earth.

    The sun is waking up after almost a decade of relative calm, scientists say — and that could cause problems on Earth.


    As more sunspots appear on the surface of our star during its active period, it may prompt more solar storms, creating bursts of electromagnetic energy that can affect everything from the power grid to GPS signals.


    These so-called solar maximums occur roughly every 11 years, and they haven't been much of a problem in the past.


    Scientists, however, fear that our reliance on electricity and interconnectivity could mean we're far more vulnerable to their effects this time around.
