Guest Post by Willis Eschenbach Someone recommended that I look at the Steinhilber 2009 paper. I did. The data is here. My first-cut graphs are below. Discuss. For the reasons I talked about in my previous post, I gotta run. Best wishes to all, I’m outta here … w.
Guest Post by Willis Eschenbach I’ve been investigating the use of the “complete ensemble empirical mode decomposition” (CEEMD) analysis method, which I discussed in a previous post entitled Noise-Assisted Data Analysis. One of the big insights leading to modern signal analysis was the brilliant idea of Joseph Fourier. He realized that any given waveform can…
I don’t know if this is a real measurement, and that the Total Solar Irradiance (TSI) measured by the SORCE project is real, or if we are seeing another sensor failure situation like what happened with NSIDC and the sea-ice measurements done by DMSP F17 satellite. Yesterday this graph of TSI plotted by SORCE was…
Guest essay by David Archibald There are a couple of interesting features of the state of the Sun at the moment. Firstly the Oulu Neutron Count has had a rapid reversal in the last few months: Figure 1: Oulu Neutron Count 1964 – 2016 The neutron count is looking like the rapid reversal during Solar…
By Frank Bosse and Fritz Vahrenholt In February 2016 our sun’s activity was, as in almost every month of the current cycle, well below the average. The observed SSN (SunSpotNumber) was 57.2. The average of the cycles 1 … 23 for this month is 80.8, thus the observed activity was 71% of the average value…

After being in a slump last month, it seems that sunspots are starting to pick up again as this latest SDO image shows: This of course is just a minor blip, as the trend is downward, as we now are on the downslope of cycle 24 activity as this plot from Dr. Leif Svalgaard demonstrates.…
“We didn’t go looking for the Maunder Minimum, it just popped out of the data.” From the UNIVERSITY OF ARIZONA Shipwrecks, tree rings reveal Caribbean hurricanes in buccaneer era Records of Spanish shipwrecks combined with tree-ring records show the period 1645 to 1715 had the fewest Caribbean hurricanes since 1500, according to new University of…
