RECURRENT LAW OF THE ACTIVE REGIONS OF PROTON FLARES

Recurrent law of the active regions for proton flares are studied in this paper. The results indicate that on the sun there are "active volcanos" of the motion along longitude, that is active reviviscent bodies of the proton flares. In 22th solar activity cycle, there are two stronger active reviviscent edes of the proton flares on the sun, they are in two latitude bands of 26°- 35°N and 20°30°S. The proton flares with peak fluses≥100pfu and ≥1000pfu produced by these reviviscent bodies are about 70.7% and 83.3% of those on the solar disk. Long periods of the revivifications for active reviviscent bodies are about 8- 11.6 years, short periods are 1-2.6 years. Due to long and short periods of the revivification for the reviviscent bodies consist with 11 years periods of the solar activity cycle and time interval of the peak years, therefore, the periodic revivifications of the active reviviscent bodies can be important cause of the 11 years periodic variation of the solar activity cycle and intensive eruptions of the flares during solar active maximum.
