Temporal coverage of each flare list considered in this study, namely RHESSI (blue), SDO/AIA (green), and Solar Orbiter/STIX (red). Plotted on top is the 13-month smoothed sunspot number showing the activity cycle of the Sun, downloaded from SILSO World Data Center (2000–2024), Royal Observatory of Belgium. The vertical black dashed lines mark the time intervals referenced in Sections 3.1, 3.2, 4.1 and 4.2 used to divide the solar cycle into its rising and decaying phases, specifically on June 1, 2010; on April 1, 2014; and on March 1, 2018.
