The reason this rash is interesting has to do with its magnetic characteristics. It is an evolving jumble of magnetic polarities, with positive (+) pressing against negative (-) in many places. These are favorable condition for magnetic reconnection and solar flares. researchers with solar telescopes are encouraged to monitor the region for further developments.
