Sun's Next Solar Cycle Predicted To Be Weaker
A new study by Sandra Chapman suggests that the sun's solar cycle can be better predicted by analyzing the sharp cutoff point of solar maxima, with Cycle 26 expected to be weaker than Cycle 25
The sun's solar cycle follows an 11-year pattern, with the current Cycle 25 beginning in 2019 and expected to decline in activity until around 2030. A new study by Sandra Chapman, published in The Astrophysical Journal, found a correlation between the number of sunspots at the cutoff point and the strength of the next solar maximum.
The study analyzed the solar activity of previous cycles and noticed that solar maxima have a sharp cutoff point, where the number of sunspots drops significantly. This correlation can be used to predict the strength of the next solar maximum. Based on the observations so far, Chapman predicts that Cycle 26 will be somewhat weaker than Cycle 25.
The next switch-off point for the sun is predicted to occur in 2028, based on Cycle 24. After this point, Chapman will have a firm prediction for Cycle 26. The study's findings will be tested by the mid- to late 2030s, when the sun's activity can be observed and compared to Chapman's predictions.
## Why it matters The solar cycle has a significant impact on our modern technological infrastructure. Understanding and predicting the solar cycle can help us prepare for potential disruptions to our technology and communication systems. The sun's variability can cause changes in the Earth's magnetic field, which can affect satellite communications, power grids, and other technological systems.
The sun's solar cycle has been observed to follow a pattern since the 1800s, but predicting exactly when solar maximum will occur and how intense it will be has been a challenge. Chapman's study provides new insights into the solar cycle and can help improve our predictions of future solar activity.
