    I must say: In a somewhat casual manner, I've become very interested in the activity of the Sun and I intuitively know it's very relevant and important to trends in human consciousness and behaviour and events occuring in Nature on Earth; and I'm intrigued and very impressed with all of this data and graphical interpretations... Cosmic rays, solar winds, particle fluxes and magenetic variation etc.; though I must admit I have no idea what any of it means - i.e. what CME's and hightened solar activity translates to, in terms of Earth and human activity...

    I'm sure I could spend the rest of my life investigating the intricacies of solar language and our relationship to it, but could anyone offer me some information on the basics of all of this information, or at least point me in the right direction so that I may be able to interpret some of it? (Preferably with some scientific basis)

    Thanks.

    Hi all , so this flare will only give us a glancing blow. What kind of effects could we possibly see and will any part of the earth be effected more than the others.

    All the graphs and images are great , but I just want to get my head around all this.

    Thanx

    Hi State!

    It all started with this:

    Quote Thu, 01 Sep 2011

    On September 1, 1859 Richard Carrington observed a solar flare while drawing sunspots. Rather than look at the same drawing of sunspots that we always see, let's look at the magnetometer records released this year by the British Geological Survey (see "Search the Collection" at this link.) Magnetometers measure the strength and direction of the Earth's magnetic field. BGS scanned and released the records from several stations, including the Greenwich station we show here.


    On the top is the day of the flare. In the oval in the upper right is the effect of the solar flare at 11:18 am. (Perhaps you can figure out the times in these plots!) Other than a few small changes, the traces on 9/1/1859 look pretty smooth.

    A coronal mass ejection, a large surge of particles from the Sun, often comes with a flare. In the lower plot are the traces from two days later, while the particles ejected from the Sun at the same time as the 9/1/1859 flare are hitting the Earth's magnetosphere. The traces cover the page, with many rapid changes. People started associating flares on the Sun with the changes in the magnetic field being measured by the magnetometers.

    This was not just scientific curiosity. Those changes in the magnetic field affected the telegraph system, shocking the operators and allowing them to send messages without batteries while the aurora caused by the solar storm pulsed overhead.

    Today we watch the Sun for signs of flares and coronal mass ejections with SDO and other satellites. We monitor the Earth's magnetic field at stations of the BGS and other organizations. Space weather continues to affect our lives when it disrupts radio communications just like it disrupted telegraphs in early September, 1859.

    This anniversary was celebrated on The Writer's Almanac, along with a poem about watching a James Bond movie.

    Happy Birthday, Space Weather!
    Here is from the Writer's Almanac:

    Quote This was the date, in 1859, of a massive solar superstorm. It's sometimes called the "perfect space storm" or the Carrington Event, after British astronomer Richard Carrington. He reported witnessing a massive white-light solar flare: a bright spot suddenly appearing on the surface of the Sun. At the same time, the Sun produced a coronal mass ejection, or CME: a large eruption of magnetized plasma. CMEs usually take three to four days to reach Earth, but the magnetic burst from the superstorm of 1859 reached us in just under 18 hours.
    While Earthlings of 1859 didn't have any cell phones, GPS units, or television signals to worry about, they were growing accustomed to rapid communication over the telegraph, which had been in use for 15 years. Within hours of the CME, telegraph wires began shorting out, starting fires and disrupting communication in North America and Europe. Compasses were useless because the Earth's magnetic field had gone haywire. The northern lights were seen as far south as Cuba and Hawaii, and the southern lights — aurora australis — were seen in Santiago, Chile. People in the northeastern United States could read the newspaper by the light of the aurora, and the Sun itself was twice as bright during the event.
    Subsequent solar storms have caused satellites, broadcast stations, and cell phones to malfunction; they've disrupted GPS systems on airplanes and have even knocked out entire power grids; in 1989, a storm much weaker than the superstorm of 1859 brought down the Hydro-Quebec power grid for more than nine hours. While scientists cannot predict the storms with any degree of confidence, some speculate that the Sun is expected to reach a period of peak activity in 2013, and the large flares often follow the peak periods. They're monitoring the Sun's activity closely, because with a little advance warning, power grids could be taken offline and satellites put in "sleep" mode for the duration of the storm, averting a global catastrophe from which it could take a decade and trillions of dollars to recover.

    G'day All,

    I logged in and was going to mention the X2.1 and associated CME's in the old "The Sun Now" sticky thread but found that we've moved here instead.
    Thanks everyone for the excellent resources supplied.
    The danger to Westernised societies of a 'Carrington Event' can not be over emphasised.
    That's why I watch for CME's and the Bz index, so as to be at least prepared.

    Avalon is an excellent resource for information sharing and collaboration on ideas (for example earth quakes and X-class/CME correlations).
    Keep up the good work!

    Update from Spaceweather.com:

    STRONG SOLAR ACTIVITY: Sunspot 1283 is crackling with solar flares. Yesterday, Sept. 6th, the active region produced an M5.3-class eruption at 0150 UT followed by a X2.1-class event at 2220 UT. NASA's Solar Dynamics Observatory recorded this extreme UV flash from the X-flare:
    The flares produced waves of ionization in Earth's upper atmosphere, briefly altering the propagation of low-frequency radio signals around our planet. Moreover, the two eruptions hurled clouds of plasma (CMEs) in our direction. CME impacts, geomagnetic storms and auroras are expected on Sept. 8-10. Stay tuned for updates.
