cgrant26 Posted May 29, 2023 Share Posted May 29, 2023 So I'm pretty new to following solar weather and specifically, magnetograms. I think I get the gist of what characteristics give sunspot regions their classifications but I wanted to get a look at one from the past that produced a big event. This is 12673 that produced an X9.3 on Sept 6, 2017. (soft X-ray flare) Wow, that's amazingly chaotic compared to what I've seen so far. Here's what it looked like just 3 days prior: 2 Link to comment Share on other sites More sharing options...

Here it is a few minutes prior to the flare, The large positive and negative polarity spot umbras are right next to each other 2 1 Link to comment Share on other sites More sharing options...

Thanks for adding that. 1 Link to comment Share on other sites More sharing options...

The only thing I know about that sunspot & date is that on September 3rd, 2017 was the last time a publically announced underground nuclear test was conducted in North Korea. I’m curious how that event might have impacted IMF conditions or solar activity at that time if at all. I agree, Sunspots sure do look like Doppler bell hooks seen in thunderstorms!
