Download Citation | Will Solar Cycles 25 and 26 Be Weaker than Cycle 24? One of the serious correlations we see is that the next solar cycle of 11 years may be the lowest in at least 200 years on our model, which calls for the low in a wave of 224 years to be precise. If the solar minimum prediction is correct, this would make Solar Cycle 24 the 7 th longest on record (11.4 years). We also show our predictions for the evolution of the Sun's polar magnetic fields for the endof Solar Cycle 24, which were used to predict the amplitude of Cycle 25. "In cycle 26… This page features our predictions and forecasts for the Sun. The maximum of Cycle 29 is expected to represent the next Gleissberg maximum. Solar Cycle 25 Prediction Panel experts said Solar Cycle 25 may have a slow start, but is anticipated to peak with solar maximum occurring between 2023 and 2026, and a sunspot range of 95 to 130. Typically, the first spots of a cycle emerge at much higher latitudes than the spots of the co-existing previous cycle, which is in its final declining phase, with spot … Bottom line: Solar cycle 24 was weak, with fewer sunspots at its peak than expected. Also, Lisa Upton, Ph.D., solar physicist with Space Systems Research Corp., states that “the expectation that Cycle 25 will be comparable in size to Cycle 24 means that the steady decline in solar cycle amplitude, seen from cycles 21 to 24, has come to an end and that there is no indication that we are currently approaching a Maunder-type minimum in solar activity.” Many have predicted an even-weaker solar cycle 25 for the coming decade. After looking at the actual sunspot numbers and solar activity, it was determined the solar cycle 24 maximum was reached in April, 2014 and peaked at an average sunspot number of 82. The number of sunspots over the entire solar cycle decreased significantly by 50% or greater. Currently, we have Solar Cycle predictions for Solar Cycles 24 and 25 (cycle amplitude and F10.7 flux). Sunspots have been observed since the early 17th century and the sunspot time series is the longest, continuously observed (recorded) time series of any natural phenomena. "In cycle 26, the two waves exactly mirror each other – peaking at the same time but in opposite hemispheres of the Sun. 1 2006, pages 29–35 Author’s Note: I was invited to write this paper by Bob [Comparing Yearly Mean Total Sunspot Numbers 1] The following was observed during the solar cycle 24: 1. predicting the sun's "weather" is hazardous to scientist's reputations - which is why the recently concluded solar cycle 25 prediction panel was done in secret with no media coverage here is a blow up (of the chart above) of what the top government scientists are saying solar cycle 25 will look like according to their… The panel agreed that Cycle 25 will be average in intensity and similar to Cycle 24. During Cycle 26, which covers the decade from 2030-2040, the two waves will become exactly out of synch and this will cause a significant reduction in solar activity. The maximum of Cycle 29 is expected to represent the next Gleissberg maximum. Prediction, (dating from 1998): Weaker Solar Cycle 24, almost non-existant solar cycle 25, 26 and likely 27. Many have predicted an even-weaker solar cycle 25 for the coming decade. The authors predict a phase shift during SC 26 that “will result in significantly reduced amplitudes of the summary curve and, thus, in the strongly reduced solar activity in Cycle 26, or the next Maunder Minimum lasting in 3 cycles Sunspot groups have a magnetic field with a north and a south pole, and, in each 11-year rise and fall, the same polarity leads in a given hemisphere, while the opposite polarity leads in the other. Our analysis also suggests a much lower value (30-40) for the maximum amplitude of the upcoming Cycle 25. Solar Cycles 24 and 25 and Predicted Climate Response by David C. Archibald This paper originally appeared in Energy and Environment,Volume 17 No. 2. In addition, Cycle 27 is expected to be stronger than Cycle 26 and weaker than Cycle 28, and Cycle 29 is expected to be stronger than both Cycles 28 and 30. So far he is a lot … On the contrary, low solar activity will probably continue for at least another year as Solar Cycle 24 decays and Solar Cycle 25 slowly sputters to life. Their interaction will be disruptive, or they will nearly cancel each other. The profile indicates that temperatures Solar Cycles 24 and 25 and Predicted Climate Response 31 At the end of solar cycle 23, sunspot activity declined to a level not seen since the year 1913. Solar cycle, period of about 11 years in which fluctuations in the number and size of sunspots and solar prominences are repeated. This charged gas moves, generating a powerful magnetic field. Our Sun is a huge ball of electrically-charged hot gas. In addition, Cycle 27 is expected to be stronger than Cycle 26 and weaker than Cycle 28, and Cycle 29 is expected to be stronger than both Cycles 28 and 30. Solar Cycle Prediction (Updated 2017/03/23) Please note:Dr. David Hathaway, a member of the MSFC solar physics group for 29 years, transferred (7/9/2014) to NASA's Ames Research Center in California, where he retired in … The Dalton Minimum was a time of minimal sunspots, a series of weak solar cycles; but it is not weak enough to be described as a Solar Grand Minima . By Cycle 25 or 26, magnetic fields may be too weak to punch through the solar surface and form recognizable sunspots at all, spelling the end of the sunspot cycle phenomenon, and the start of another Maunder Minimum cooling period perhaps lasting until 2100.
