Histograms showing the 24-h evolution of sunspot groups starting as a DSO-type McIntosh classification (a), with bars representing the percentage of evolutions observed starting as DSO and evolving to a sub-group of McIntosh classifications. The corresponding evolution-dependent ≥C1.0 and ≥M1.0 flaring rates are shown in panels (b) and (c), respectively. Histogram bars are coloured by evolution: no evolution (black); upward evolution (dark red); downward evolution (light blue).
