There is current talk about the arrival of solar maximum heralded by magnetic polarity change.
Two previous Talkshop articles mentioned precursors, the “Iron line” and more importantly results from the JAXA / Solar-B earth orbit satellite which is able to get a better look at the solar polar regions than is possible from earth. Magnetic domains can be deduced from radiation which provided an early look as the solar north pole flipped polarity, leading the south pole.
Today we see that the Wilcox solar observatory data is showing their data has crossed to opposite polarity.
Solar-B is an old satellite. It’s successors are being planned, with Solar-C launch due 2018. A “Solar science meeting” took place earlier this year at St Andrew’s university, fitting perhaps given the long affinity between Japan and Scotland.
The meeting documents, PDF, DOC and Powerpoint are online.
Both ESA and NASA representatives were invited but sent apologies.
Of particular interest to Talkshop regulars is the presentation given by Sami K. Solanki: How can Solar-C address the issue on the long-term solar variability and the Earth climate? (5.3M PDF from PPT)
This is dealing with TSI and I seem to be thinking much the same, there is devil in the detail involving very short wavelength radiation and with magnetics of critical importance. Solar A B C D are important.
Meeting results are here, part of “SOLAR-C Working Group, JAXA/SOLAR-C Preparatory Office, NAOJ”
