A QUIET SUN: 4 DAYS SPOTLESS – WHAT DOES IT MEAN?
The Sun has been spotless indicating a generally very low solar activity for 4 consecutive days already. It is currently transitioning towards the solar minimum, the period in the roughly 11-year solar cycle when less solar activity is expected. This was anticipated to be reached between 2019 and 2020. Basically, the relatively cool and dark areas on the Sun’s photosphere, known as sunspots, appear and vanish due to violent twisted magnetic field interactions with its surface plasma.
