Phase coherence of solar cycle minima over two 178-year periods
We compare the phases of solar cycle minima with an ''ideal'' sunspot cycle of the mean period of 11.14 years. The observed departures from the ideal model form a pattern over 16 cycles (approximately 178 years) which appears to be repeated over the next 16 cycles. Both in mathematic sign and amplitude the two 178-year cycles are coherent to a statistically significant level of 98%. If true, this furnishes a basis for predicting sunspot cycle minima.
