This scientific study utilizes Solar Dynamics Observatory data from 2010 to 2025 to analyze the magnetic field variations within the Sun’s quiet regions. By examining millions of small-scale structures, the researchers discovered that the total magnetic flux in these quiet areas fluctuates in alignment with the standard eleven-year solar cycle. Interestingly, the data reveals a dual behavior where smaller magnetic structures decrease as sunspots increase, while larger structures grow more numerous during peak solar activity. An empirical model suggests that during active periods, over half of this quiet-region flux originates from the remnants of decayed active regions. Ultimately, the authors argue that the solar cycle should be measured by the magnetism of the entire solar surface rather than by sunspots alone.
