A BIG UNSTABLE SUNSPOT: Giant sunspot AR3190 is turning away from Earth. It's still dangerous. The reason why is shown in this magnetic map from NASA's Solar Dynamics Observatory: https://imgur.com/nxDAubx The sunspot's primary dark core is actually a huge pole of negative (-) magnetism closely surrounded by multiple islands of positive (+) polarity. This is exactly how solar flares get started. When + and - bump together in close proximity, magnetic reconnection can cause tremendous explosions. AR3190 poses a threat for X-class solar flares.Even though AR3190 is not facing Earth, the broad spray of any X-flare will still illuminate our planet with X-rays and extreme UV radiation. Radio blackouts and other effects remain possible as long as we can see the departing sunspot. [ link to www.spaceweather.com (secure)]
