Abstract Energetic protons that cause polar-cap absorption (P CA) come from flares that cluster in certain preferred heliographic longitudes. This clumping of great flares at locations that are fixed in a rigidly rotating system is distinct from the recurrence or revival of individual long-lived active regions. The clustering of PCA flares is related to the clustering of optical solar activity found by Trotter and Billings in cycle 19, but the grouping of PCA flares is much sharper. The results of sunspot studies by Losh and by Vitinskii are shown to be consistent with each other when both are presented in the same form.
