Attributes of 5557 SHARP-associated flares over September 2012 to May 2019. (a) Flare onset times, in terms of GOES classes X (red), M (orange) and C (green) and respective sub-classes (tick marks; right ordinate), plotted over the 90-day averaged sunspot number over Solar Cycle 24 (left ordinate; Source: Sunspot Index and Long-Term Solar Observations [SILSO], Royal Observatory of Belgium). The numbers of flares for each GOES class are also given. The bottom line shows waterfall diagrams of the distributions of rise time (b), decay time (c) and duration (d). Extrema for each distributions are shown in each plot. The “All flares” diagram corresponds to the sum of flare numbers in each bin. We use fixed, 10-min bin sizes.
