The NOAA Space Weather Prediction Center has updated their monthly graph set and it is becoming even more clear that we are past solar max, and that solar max has been a dud. “The slump” continues not only in sunspot activity, but also other metrics. And, tellingly, Dr. David Hathaway has now aligned his once…
Sunspot count is virtually unchanged from last month : It seems possible that we’ve seen the double peak, and it will be downhill after this.
Guest essay by David Archibald Recently, a number of newspaper articles spoke of the potential of cycle 25 to be “Weakest Solar Cycle In Almost 200 Years”. “We’re in a new age of solar physics,” said David Hathaway of NASA’s Marshall Space Flight Center in Huntsville, Alabama. Here is a collection of solar measurements that…
It is looking more and more like a double sunspot peak for solar cycle 24. Sunspot count is down again: A similar drop occurred in radio flux.
The data from SWPC is in, and it is lethargic at best. Sunspot numbers took a hit, down to about 42, a delta of ~50 lower compared to the red prediction line. 10.7 cm solar radio flux took a similar hit:
Note: See also the 1997 regime change in global climate data by the same method, here I’m happy to report that something I recognized and reported back in 2008 related to solar data has been independently confirmed by another source, and was a surprise when it showed up in my inbox two days ago.

The sunspot number for February from SIDC is down again, to 33.1 Here’s the source of that data: http://sidc.oma.be/DATA/monthssn.dat So far, cycle 24 is significantly lower in SSN number that the last three cycles, in addition to having a delayed start. While the delta of the drop in Feb 2012 is not unusual by itself,…
