A new method for predicting speed and motion of solar flares

A Montana State University physicist who has developed a new model that predicts the speed of solar plasma during solar flares, likening it to the path traveled by a thrown baseball, will present his findings at the Solar Physics Division of the American Astronomical Society conference being held this week in Boulder, Colorado. Sean Brannon,…

Solar Cycle Update – spotless

So Constant And Unspotted Didst Thou Seem1 Guest essay by David Archibald The image of the Sun today is spotless. This is the first spotless day of the 24-25 solar minimum. Not a great deal can be read from that. According to Wilson, for cycles 9-14, sunspot minimum followed the first spotless day by about 72 months,…

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 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…


Solar Update March 2016

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…
