Over the weekend, we reviewed the state of the solar data for March 2017. Now, there’s a two week straight lack of sunspots, the longest stretch since 2010. Overview The sun is currently blank with no visible sunspots and this is the 14th straight day with a blank look which is the longest such stretch…
Guest essay by David Archibald Our divination of solar parameters is aimed to elucidating two things – the length of Solar Cycle 24 and the amplitude of Solar Cycle 25. Figure 1: F10.7 Flux from 2014 The F10.7 flux was exhibiting high volatility up to the beginning of 2015 after which it entered a disciplined…
Bruiser Murray writes: Several times I have commented that the BOM has falsified Solar Exposure data for 2013. Recently “Griff” challenged me to substantiate the claim. I have not had access to my old computer where some of the files were stored so, until recently, could not provide the evidence. That changed last week and…
From the University of Reading: Britain may lose the magic of the Northern Lights by the middle of the century due to major shifts in solar activity, scientists have discovered. Space scientists at the University of Reading conclude that plummeting solar activity will shrink the overall size of the sun’s ‘atmosphere’ by a third and weaken…
Dr. Leif Svalgaard writes advising me of this new paper published Jan. 17. After reading it, I’ll have to say that it isn’t a matter of “if” – it’s a matter of when we’ll get another CME like the Carrington Event in 1859 – which had it occurred today, would plunge our society into darkness…
Guest essay by David Archibald One of the most accurate ways of predicting the amplitude of the next solar cycle is to derive it from the strength of the solar polar fields at solar minimum. And you don’t have to wait for solar minimum. An accurate assessment can be made four years before minimum, which…
By Sebastian Luening, Frank Bosse and Fritz Vahrenholt Introduction On 14th November 2016 Stefan Rahmstorf (“stefan”) of the Potsdam Institute for Climate Impact Research (PIK) published on the climate blog Realclimate an article entitled „Record heat despite a cold sun”. In this article he discusses a temperature prognosis which we first published 2012 in the…
