The occurrence rate of solar flares exhibits a periodicity of about 152 days. The cause of the 152-day periodicity still remains a mystery. But answers to the following questions will enhance understanding of it. (1) Is the periodicity a local or a global phenomenon? (2) Is the periodicity due to the interaction of 'hotspots' rotating at different rates such that they align with one another once every 152-day period? (3) Is the periodicity due to the interaction of rotating features originating from g-mode oscillations? Here the authors report an analysis of 'major flares' observed with the Hard X-ray Burst Spectrometer (HXRBS) aboard SMM and conclude that the 152-day periodicity is a global phenomenon, and that the answers to questions (2) and (3) are negative.
