Relative number of flares (top) as well as percentage of flares identified as ELPs (bottom) as a function of the Mount Wilson magnetic classification of the flare-harboring sunspot region for all flares with a GOES class exceeding C3.0 (black), all ELP flares (orange), as well as the eruptive (red) and confined (blue) portion of ELP flares. The y-axis in the top panel displays the share of flares belonging to the respective group divided by the total number of flares in this colored category (in %).
