Hemisphere and total SSN updated to March. Acid, where can we see the full chart and a legend? |

Thanks Acid. Now, some commentary from spot watchers? (I'm a wriggle watcher.)  |

You can't argue that the NH and SH are synchronized yet but each week will bring some clarity.
If they are, cycle 25 will in essence be a small cycle. Exciting!

Thanks Acid. Now, some commentary from spot watchers? (I'm a wriggle watcher.) Undoubtedly 25 current peak is higher then 24. 25 was predicted to peak in 2025. Regarding overall strength, the dissimilarity in 24s peak came predominantly from the activity in the later Nh peak. 25s current peak was a result of both hemisphere being broadly equally active. I wonder if a simple equation along the lines of total cycle sunspot amount/time might produce different cycle strength values to peak ssn in a meaningful way? |

Do I see a new, tested equation in your future?  |

Beyond my pay grade but a graph showing the addition of the NH and SH respecting sign would show the asynchronicity of the cycles.
the cycle size is more about aggregate than moment in time peak.

There obviously would be a difference. My presumption is it's been looked at previously and the difference is small. I've noted here before that I read that the 13-year smoothing period was chosen because it is a time period which gives a good correlation between the sunspot number maximum and the 10.7 CM Solar Radio Flux maximums. |

Don't know if this helps. But here is a visual.  |

www.spaceweather.com/POTENTIALLY DANGEROUS SUNSPOT: New sunspot AR3615 is complicated. It looks more like a rash than a sunspot, with a dozen-plus dark cores scattered randomly over a wide area. A magnetic map of the region shows why it is potentially dangerous:
