Heartbeat of the Sun from Principal Component Analysis and prediction of solar activity on a millenium timescale
We derive two principal components (PCs) of temporal magnetic field variations over the solar cycles 21–24 from full disk magnetograms covering about 39% of data variance, with σ = 0.67. These PCs are attributed to two main magnetic waves travelling from the opposite hemispheres with close frequenci...
