- W88573280 abstract "Solar cycle variations in the 27-day recurrence of geomagnetic activity during cycles 17-21 are examined using an event analysis technique rather than the usual approach of time series analysis. The events were recurrent storm days, i.e. days of high geomagnetic activity (A p ≥30), which fell 27 days after a similar day. The observed numbers of events are compared against those expected from chance coincidence using the well-known χ 2 statistic. Thus it is straight forward to assess the statistical significance of any changes in the rates of occurrence of events. This analysis shows that there were significant peaks in the rate of occurrence of 27-day activity in the second half of the declining phase of each cycle. This peak was much larger for the two even-numbered cycles than for the three odd-numbered cycles. Thus we may conclude that the solar cycle modulation in the 27-day activity was more marked in the even-numbered cycles than in the odd. This evidence suggests that there is a double solar cycle in 27-day activity. It is shown that this result is consistent with in situ observations of co-rotating streams for cycles 20 and 21" @default.
