Abstract : INHOMOGENEITIES AND INCONSISTENCIES IN THE PUBLISHED INTERNATIONAL FLARE DATA PRESENT THE NEED FOR CRITICAL EDITING OF THESE DATA BEFORE THEY CAN BE TREATED STATISTICALLY. After suitable correction, observed monthly incidence of flares is tabulated. Hours of effective parol must be calculated from hours of actual patrol. When these data are available, actual hemispheric flare incidence can be estimated. Flare incidence thus found is correlated moderately well with sunspot number, and with the rate of formation of new active regions. The same analysisALSO PROVIDES INFORMATION ON THE RELATIVE FREQUENCY OF FLARES OF DIFFERENT IMPORANCE. Kleczek's imporices. The apparent average drations of flares change secularly, but this undoubtedly is the result of improving methods of observation. (Author)
