Abstract
PERIODICITIES of less than 27 days in geophysical disturbance data have been investigated for many years, with inconclusive results, due to inherent difficulties in determining the statistical significance of the computations. However, there is now an increasing amount of evidence, arising from the examination of independent data samples, to support the existence of such periodicities. Some of the recent evidence is summarized here.
