Solar activity during the last millennium, estimated from cosmogenic in-situ C14 in South Pole and GISP2 ice cores
Entry ID: NSF-ANT05-38683


Summary
Abstract: The principal aim of this research is to determine the precise manner in which solar activity has varied in the past 1000 years. During this period, four periods of very low solar activity have been identified: Wolf (1305-1345 AD), Spoerer (1418-1540 AD), Maunder (1645-1715), and one period of high solar activity (1100-1250 A.D.) have been deduced based on available historical records of sunspot ...
