VAN ZELE, María Andrea. The choice of the geomagnetically quiet days. Geoacta [online]. 2013, vol.38, n.2, pp.107-127. ISSN 1852-7744.

Quiet geomagnetic variations in low and middle latitudes are those due to the movement of ions and electrons in the ionospheric E region. To study these variations (Sq), disturbances and storms, it is necessary to identify which days may be considered as quiet. The aim of this work is to demonstrate the presence of variations due to different causes in some of the 5 quietest days a month (even with the same level of geomagnetic disturbance) and show that the identification of those days (Q) should be made for each particular case.

Palabras clave : Quiet geomagnetic variations; Sq; Selection criteria.
