Secrets of Sunspots and Solar Magnetic Fields Investigated in NASA Supercomputing Simulations
New results based on simulations out of NASA’s Advanced Supercomputing facility at NASA’s Ames Research Center in California’s Silicon Valley are painting a more complete picture of one of the…
Sunspots and El Nino Part Two
Guest post by Willis Eschenbach In my last post, The Sun Also Sets, I looked at a study that I’ll continue to call L2021. It claimed a correlation between what…
A new look at sunspots
NASA’s extensive fleet of spacecraft allows scientists to study the Sun extremely close-up – one of the agency’s spacecraft is even on its way to fly through the Sun’s outer…
A Solar Science Timeline – sunspots, cycles, and solar wind
Humankind has studied the Sun for millennia. Ancient Babylonians recorded eclipses on stone tablets. Renaissance scientists peered through telescopes, tracking sunspots. Eventually we took to space, and the first satellites captured solar particles…
Sunspots, Verse 25
Guest Post by Willis Eschenbach [See update at the end] I started out as a true believer that sunspots (or something that changes in sync with sunspots, like heliomagnetism, cosmic…
Reverse Polarity Sunspots appear on the Sun – ending a 39 day stretch of spotless days
Dr. Tony Phillips writes: A new solar cycle is coming. Today, two sunspots emerged on the solar disk. Their reversed magnetic polarity marks them as members of new Solar Cycle…
Plasma flow near sun’s surface explains sunspots, other solar phenomena
University of Washington For 400 years people have tracked sunspots, the dark patches that appear for weeks at a time on the sun’s surface. They have observed but been unable…
Amid the dimmest Sun since 1978 – a month without sunspots
The sun today is cue-ball blank, a perfect unmarred sphere: The sun has just passed an entire calendar month with no sunspots. The last time this happened, in August 2008,…
Sunspots: Labitzke Meets Bonferroni
Guest Post by Willis Eschenbach In a previous thread here on WUWT, a commenter said that the sunspot-related variations in solar output were shown by Labitzke et al. to affect…
Scottish Sunspots
Guest Post by Willis Eschenbach [See Update At End] In a recent post, Anthony published Leif Svalgaard’s new paper showing 9,000 years of reconstructed solar activity. Svalgaard paper: Reconstruction of…
Oddly quiet sun: 3 weeks without sunspots
The sun has been blank for 21 straight days–a remarkable 3 weeks without sunspots. This is an almost decade-class event. The last time the sun lost its spots for 21…
NASA: Sunspots Vanishing Faster than Expected
by Dr. Tony Philips, NASA Spaceweather Sunspots are becoming scarce. Very scarce. So far in 2018 the sun has been blank almost 60% of the time, with whole weeks going…
Paintings, sunspots and frost fairs: Rethinking the Little Ice Age
The whole concept of the ‘Little Ice Age’ is ‘misleading’, as the changes were small-scale, seasonal and insignificant compared with present-day global warming, a group of solar and climate scientists…
Chinese Sunspots
Guest Post by Willis Eschenbach [See also the new Update at the end of the post.] I see that there is a new paper from China causing a great disturbance…
CEEMD and Sunspots
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…
The Cattle Cycle, Sunspots, Climate Changes and the Orbital Interactions of the Gas Giant Planets
[Note, I don’t necessarily agree with the conclusion this publication, as it smacks of barycentrism, which I don’t give any credence to, but it does discuss some other concepts, and…
Sunspots and Norwegian Child Mortality
Guest Post by Willis Eschenbach In January there was a study published by The Royal Society entitled “Solar activity at birth predicted infant survival and women’s fertility in historical Norway”, available…
Early Sunspots and Volcanoes
Guest Post by Willis Eschenbach Well, as often happens I started out in one direction and then I got sidetractored … I wanted to respond to Michele Casati’s claim in…
Volcanoes and Sunspots
Guest Post by Willis Eschenbach I keep reading how sunspots are supposed to affect volcanoes. In the comments to my last post, Tides, Earthquakes, and Volcanoes, someone approvingly quoted a volcano…
Sunspots and Sea Surface Temperature
Guest Post by Willis Eschenbach I thought I was done with sunspots … but as the well-known climate scientist Michael Corleone once remarked, “Just when I thought I was out…
Cosmic Rays, Sunspots, and Beryllium
Guest Post by Willis Eschenbach In investigations of the past history of cosmic rays, the deposition rates (flux rates) of the beryllium isotope 10Be are often used as a proxy…
Usoskin Et Al. Discover A New Class of Sunspots
Guest Post by Willis Eschenbach There’s a new post up by Usoskin et al. entitled “Evidence for distinct modes of solar activity”. To their credit, they’ve archived their data, it’s…
Sunspots and Sea Level
Guest Post by Willis Eschenbach I came across a curious graph and claim today in a peer-reviewed scientific paper. Here’s the graph relating sunspots and the change in sea level:…
