    Thanks for making this series of posts.

    What technology is used to determine the polarity of a sunspot?

    Really enjoy this info. I'm about the most undisciplined amateur EVER, but I try really hard never to miss an episode. SO informative.

    Great information for Amateur Radio propagation. It looks like cycle may have started. Keep up the good work.

    After a bit of digging, I can answer my own question, info on the instrumentation used in
    modern times would still be interesting to hear about.

    "In 1908, he used the Zeeman effect with a modified spectroheliograph to establish that sunspots were magnetic.
    Subsequent work demonstrated a strong tendency for east-west alignment of magnetic polarities in sunspots, with mirror symmetry across the solar equator; and that the polarity in each hemisphere switched orientation from one sunspot cycle to the next."

    A more broad-scope article on sunspots:
    mentioned another interesting characteristic of sunspots.
    "Early in the cycle, sunspots appear in the higher latitudes and then move towards the equator as the cycle approaches maximum, following Spörer's law."
