Solar activity: Where have we been and where might we be going?
Is the Sun in Transition? The Unusual Cycle 24, and Implications for the Solar-Stellar Connection
University of Reading
To predict how the solar magnetic field may vary in the future, we first need to understand how it has varied in the past. Reconstructing solar activity further back in time necessitates relying on increasingly indirect proxies, from in situ spacecraft measurements (~60 years), to geomagnetic measurements (~150 years), sunspot observations (400 years) and, finally, cosmogenic isotope records (~10,000 years). I'll review what these are, what exactly they tell us and how much they can be trusted. I'll also, possibly imprudently, speculate about the most likely scenario for solar activity over the coming decades.
