Volunteers Find Oddly High Solar Flare Rates
2 min read Volunteers Find Oddly High Solar Flare Rates Patches of the Sun’s surface often show strong magnetic fields. These fields can emerge within a matter of hours, and can decay slowly or quickly, sometimes over days, weeks, or even months. Thanks to a new study about these long-lived active regions , we now know much more about the patches where these strong magnetic fields take at least a month to decay. This study relied on inputs from NASA’s Solar Active Region Spotter citizen science project, which asked volunteers to answer a series of questions about pairs of active region images from NASA’s Solar Dynamics Observatory. Project leads Emily Mason (Predictive Science Inc.) and Kara Kniezewski (Air Force Institute of Technology) looked at the data and the analysis done by volunteers. They found that the long-lived active regions produce disproportionately more flares than the shorter-lived regions and are 3-6 times more likely than other active regions to be the sour...
