evidence: Our Sun Is Going Into A 'Lockdown', But Don't Panic As It Won't Cause Any Calamities On Earth Sun's going into 'lockdown': What does this mean for the Earth and all of us living on it? [...] Sun's lockdown or solar minimum, as its rightly called, is part of the solar cycle where the sun's magnetic pole flips. Since the sun's magnetic field controls the sun's overall activity, during the flipping of its magnetic poles it experiences solar minimum or reduced level of activity -- as indicated by reduced number of sunspots and flares, for instance.
