Solar Activity Record from Archeomagnetic Data

Each of the available solar activity (SA) proxy data (historical notes, radio nuclides ¹⁴C and ¹⁰Be production) are contaminated by their specific noise factors. So, any additional proxy with its independent noise factors will essentially increase the accuracy of composite SA restorations. It is proposed here that archaeomagnetic measurements 95% confidence interval (α₉₅) may serve as new proxy for the SA estimation in the past. This proxy is compared with other available proxies during the years 1500–2000.
