Webis the regular daily variation that is clearly observed during geomagnetic quiet time periods. The observed regular daily variations are often referred to as the geomagnetic daily variation or the solar quiet (Sq) variation. Given its promi-nence, the geomagnetic daily variation has attracted signifi-cant attention and been extensively studied.
