摘要：
A method for determining quiet daily variations (Sq curve) in automatic mode and calculating the K index of geomagnetic activity based on wavelet packets has been proposed. The method makes it possible to reproduce the Bartels technique and includes the separation of geomagnetic signal informative components, determination of geomagnetic field disturbances, and the formation of quiet daily variations. The method effectiveness was proved experimentally.
