170 sunspots today.

Don’t pay too much attention to fluctuations—look at SC24 to see even bigger ones.

As well as sunspots this cycle has seen more flares, more coronal mass ejections etc. The sun is significantly more active now than in SC24.

In reply to markedup2. markedup2: The system is arbitrary, but the Earth-facing hemisphere was only observable piece of information for centuries. Holding to that system allows new data to match old data, thus continuing the measure of solar activity in a consistent way. None of this precludes gathering data now from the Sun's other hemisphere, using space probes. This system merely allows us to continue measuring the solar cycle in the same manner as before.

“the Sun’s Earth-facing hemisphere” is that a useful thing?

It is a constantly changing hemisphere because the sun rotates and Earth revolves. It seems a like a fairly arbitrary (although easy to look at) definition of “hemisphere”.

Sun Spots are suppose to have bigger effect on our weather then dose our modern way of living

Is the Sun’s unpredictable behavior the actual issue, or is it that we have no learned accuracy in evaluating a chaotic, naturally occurring system, with anything approaching confidence in our own powers of deduction?

Figuring out the natural behavior of the sum seems secondary to figuring out our own.

Interesting observation on the (approximate) 100 year cycle of maxima.

Thanks as always for the solar info.. We’re still in an interesting phase where it’s hard to predict.. Keep up the good work.
