    The speed of light ??

    How do predict the Aurora Borealis
    The sun flares have already happened
    Are they predicting more
    or is the radiation that causes the Aurora Borealis traveling slower than light

    What are you wibbling about?
    You've answered your own question and provided a link to a more detailed explanation.

    Right then, a simply as I can:
    1. The scientists saw some solar flares.
    2. The flares eject a stream of charged particles (which, as you suggest, travel slower than light).
    3. Those charged particles hit our planet's magnetic shield and produce the pretty patterns in the sky.


    Hope that helps.

    wot 'e sed.

    Alternatively read "Inconstant Moon" by Larry Niven

    (or if you can't be bothered reading.. wait for it to be repeated on the TV series Outer Limits.)

    whenever we "see" something happening on the Sun we're already 8 1/2 mins late as the sun is approximately 8 1/2 light minutes away.
