Sun unleashes X-5 Class solar flare

March 7, 2012 SPACEMajor Solar Flare: Big sunspot AR1429 has unleashed another major flare. This one is the strongest yet, an X5-class eruption on March 7th at 00:28 UT. NASA’s Solar Dynamics Observatory recorded the extreme UV flash: This eruption hurled a bright CME into space, shown here in a movie from the Solar Dynamics Observatory. Although the CME is not squarely Earth-directed, it appears direct enough to deliver a glancing blow to our planet’s magnetic field on March 8-9. This would add to the magnetic unrest already underway at high latitudes. The flare also accelerated energetic protons toward Earth, triggering an S3-class solar radiation storm, in progress. Such a storm is mainly a nuisance to satellites, causing occasional reboots of onboard computers and adding noise to imaging systems. –Space Weather

    X5.4 Major Solar Flare from Region 1429 – March 7, 2012

    Updated 03:28 UTC March 7 2012 :

    A major X5.4 solar flare has just occured at 00:24 UTC March 7, 2012.
    This X5.4 flare came from sunspot region 1429.
    Sunspot region 1429 is Earth directed.
    There was a large CME produced with this X class event.
    This event produced a R3 radio blackout.

    Updates coming as we have more information!
    Keep checking back

    Update on the solar flares:
    just issued from NOAA

    2012-03-07 01:03 Strong Solar Eruption; Earth-Directed CME Likely
    An R3 (Strong) Radio Blackout is now in progress, beginning about 7:00 p.m. EST today. The site of the eruption, previously active Region 1429, is now near center disk, so there’s high-potential of an earth-directed CME. In addition, expect the imminent beginning of a Solar Radiation Storm. Analysis now occurring on both fronts
    http://www.swpc.noaa.gov/

    the Xray flux was slowly dropping after the X5.4 solar flare, it dropped to around the X1.0 level, and is right now on a slow rise back up
    http://www.swpc.noaa.gov/rt_plots/xray_1m.html

    currently at a X1.3
    this is seen happening a lot of the time when there is a CME produced with the associated solar flare

    Here we see this X flare on sdo EVE

    As posted on the other solar article, there was major solar actvity prior to both the Chilean abd Japanese megaquakes, all happening while the sun is in Aquarius where a pitcher or vial is being poured out. Some theories on Revelations see seals, vials, and trumpets intertwined or sequencing with one another. I do not favor the “rapture” THEORY so I believe we will witness all of Revelations.

    Power systems: high-latitude power systems may experience voltage alarms, long-duration storms may cause transformer damage.
    Spacecraft operations: corrective actions to orientation may be required by ground control; possible changes in drag affect orbit predictions.

    SOLAR RADIATION STORM – UPDATE

    Scale of S3
    Strong

    Biological: radiation hazard avoidance recommended for astronauts on EVA; passengers and crew in high-flying aircraft at high latitudes may be exposed to radiation risk.***
    Satellite operations: single-event upsets, noise in imaging systems, and slight reduction of efficiency in solar panel are likely.
    Other systems: degraded HF radio propagation through the polar regions and navigation position errors likely.

    With this major flare coming towards earth over the 8-9 and the 8th also showing a full moon to us all and the one year aniversery of the epic tsunami in Japan , is there a chance for some major global disturbances and would you go as far to say that these events make the next few days HIGH in regard to chance of geological movement.

    I wonder if my professor will except the fact that I’m not leaving my home town in Califonia for the rest of the week due to the chance of a major Earthquake?

    Thank you Yamkin. I was wondering what the effect would be for those flying in high-altitude aircraft.

    I have a feeling that this one will be a major flare. Even The Weather Channel is talking about it. And I have a feeling that the Sun isn’t done yet with flares.

    SIDC – RWC BELGIUM Wed Mar 7 2012, 2208 UT

    A possible interplanetary shock wave was detected by SOHO/CELIAS at 12:00 UT today, although the corresponding jump in the interplanetary magnetic field magnitude is unclear in the ACE data. The shock is probably associated with the full halo CME observed on the Sun on March 5. The southward IMF in the post-shock flow resulted in another intervals of K = 6 and K = 5 reported by NOAA. The solar wind speed in the post-shock flow reached 580 km/s. Due to this increase in the background solar wind speed, we update the prediction for the arrival time of the interplanetary counterpart of the full halo CME observed on March 7: we expect the ICME arrival around noon on March 8.

    For what its worth, the msm is playing this down, saying that it might effect the satellites, but nothing big will happen as usual. Then the next thing they mention is the threat of a “cyber attack” that could take down the power grid! Then they talk about the apparent possibility of a military “intervention” in Syria! Then they talk about the possibility of Iran developing a nuclear weapon much sooner than people think! Ya know, something fishy, and it stinks, really bad!

    MAGNETOSPHERE HAS DRAMATICALLY DIMINISHED. The angle of the solar wind By(nT) has dramatically gone negative. Proton levels are at an EXTREME level. Further earthquakes, volcano activity and other disasters will be greatly influenced by the cosmic rays striking the earth’s core which is also contributing to the heating of the earth’s core.

    há cerca de um minuto.

    The Bz component of the Interplanetary Magnetic Field (IMF) has been pointing mostly to the north and this is keeping the geomagnetic storm at minor levels thus far. Should the Bz begin to point south for long durations, this may help intensify the storm. More updates when needed.

    What does the “Bz” mean?

    The sun has a magnetic field which the solar wind can carry throughout the solar system. This is called the Interplanetary Magnetic Field (IMF). Earth also has a magnetic field which forms a bubble around our planet. This is called the Magnetosphere. This bubble deflects the solar wind. Earth’s magnetic field comes into contact with the sun’s magnetic field in a place called the magnetopause. Here is the catch. Earth’s magnetic field points north. When the sun’s magnetic field points south, also known as southward Bz.. it may cancel Earth’s magnetic field at point of contact. When the Bz is south the 2 fields link up. This basically opens up a door that may allow energy from the solar wind to reach Earth’s atmosphere. http://www.facebook.com/SolarHam

    This small CME has had a northward orientation cauusing it to make little connection. It is not going to do much. This is the first of two. This was the small one. The larger one is not set to arrive for another few hours and will be smashed into the rear end of this one. Here are the times these storms were scheduled to arrive today. So far everything is on schedule.

    Here is the first one that we are in now.
