The sun is as blank as a billiard ball, solar activity dwindling to lows not seen in 200 years
WUWT
The last time sunspots vanished for a whole week was in
Dec. 2010–a time when the sun was bouncing back from a long Solar
Minimum. In this case, the 7 week interregnum is a sign that a new Solar
Minimum is coming.
The sunspot cycle is like a pendulum, swinging back and forth every
11-years or so between times of high and low sunspot number. The next
low is expected in 2019-2020. Between now and then sunspots will become
increasingly rare with stretches of days, then weeks, then months of
“billiard-ball suns.”
