Scary, but not really scary!

A half a million miles long ‘solar whip’ is on the surface of the sun. The radiation from the eruption will create a geomagnetic storm. It will hit earth today. We are the audience. We watch big games. No, we do not play with fire.

    Scientists have long predicted that a single solar storm could wipe out our communications infrastructure in a few hours but the probability is extremely low. Think of the surface area of a sphere of 93 million miles and the diameter of the earth of 4000 miles. It does not matter whether the distances are measured in kilometers or miles, since we are only interested in the ratio. There is a very low chance of actually getting hit by a great lance of magnetic plasma.

    R = distance to sun 93000000

    r = radius of earth 4000

    (PI*r*r) % 4 * PI * R * R

    = r*r % 4 * R * R = (r%2*R)^2

    = (2000 % 93000000)^2 say.

    $ X<- 2000.0%93000000

    $ X*X

    Very nice images. I do not understand why they are tagged under atheism though.

    Not fire but hotter still
    This plasma of the Sun
    Entwined it curls
    Springs magnetic lines
    It leaps and dances on.

    Against the void
    Our daytime star
    Is haloed by such stuff
    Corona fiery an AU off
    Glory in each one.

    How many flares and spots and blasts
    From aeons since its birth
    Our local star that shines so far
    Long may its beauty last

    (But please no major solar storm that takes out satellites, power grids and worse!)

    Cheers Taslima, great clip. :-)

      PS. One of the best books I’ve read this year is this one :

      http://www.stuartclark.com/publications/2-publications/4-the-sun-kings

      on the how we’ve learnt about the Sun and solar flares and storms and their associated earthly effects over time especially focusing on Richard Carrington who witnessed what is still the hugest solar flare ever known back in 1859 but including a lot more too from William Herschel’s belief in our Sun as inhabited and earth-like (Really!) to SOHO’s recent space based studies. I’d highly recommend it, great read.

      Hope its okay to link to that book here – apologies and please let me know if not.

        You are awesome.

          Aww.. Thanks Taslima. (Can feel my head swelling already.)
