Notes. The SC column refers to the analysed solar cycle. AL denotes the Carrington longitude of the AL at its peak activity (given as Peak time [CR]), corresponding to the centre of the brightest regions in the 2D KDEs derived from the sunspot group and solar flare data. The table also includes the width of each identified AL (in degrees) and its lifetime (in CRs). In the final three rows, the average (avg.), standard deviation (std.), and median (med.) values of the ALs’ widths and lifetimes are provided.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
