Three weeks without sunspots
The sun has been blank for 21 straight days--a remarkable 3 weeks without
sunspots. This is an almost decade-class event.
The last time the sun lost its spots for 21 consecutive days was in the
year 2009 coming on the heels of an historic solar minimum.
With the current stretch of blank suns, solar minimum conditions have
definitely returned.
