The present paper investigates the statistical behaviour of the solar flares through cycle 21 (1976-1986). The total number of solar flares and the number of flares of various importance are given. The year of maximum of all events was 1980 with 10132 flares. The subflares háve had their maximum values in 1979 (9278 events)
and in 1980 (9273 events) while, the other flares reached the maximum two - three years later. The asymmetry A for subflares and importance 1 flares favour the Southern hemisphere (A= -2.8 and -0.9) but thal of importance >2, the northem hemisphere (A=
+3.6). The maximum number of flares with importance >2 (Fmax) in solar cycle 21 took place two years later than the maximum number of solar spots (Rmax) but Fmax in cycle 20 appeared one year before Rmax and for cycle 19 in the same year of Rmax.
