Spotless Sun | Solar Cycle # 24 weakest in more than a Century

Not a single sunspot since June 3rd. However, solar activity of course continues modulating geomagnetism,
 and in some two or three days sunspots
should reappear from region #12,546, currently still on the sun's farside.
The current Solar Cycle # 24 is the weakest solar cycle in more than a century with the fewest sunspots since
Solar Cycle # 14 peaked in February 1906.
The Sun rotates counterclockwise, but not as a rigid sphere:
The equator rotates faster than the poles (differential rotation).
