Solar Maximum May Be Approaching

We may be nearing the maximum of Solar Cycle 25, based on observed weakening of the sun’s north and south poles. According to SpaceNews, this is typical as solar max approaches, as the polarity of the sun’s poles reverses with each new cycle. 

According to the report, recent measurements by NASA’s Solar Dynamics Observatory, or SDO, indicate that the magnetic fields in the sun’s polar regions are rapidly weakening and are likely to disappear entirely before flipping polarity. This phenomenon has been observed at the peak of every solar cycle since scientists learned how to measure the strength of the sun’s magnetic field.
