WebJul 13, 2015 · All of their modelling predictions and observations were closely matched. "Looking ahead to the next solar cycles, the model predicts that the pair of waves become increasingly offset during Cycle 25, which peaks in 2024. During Cycle 26, which covers the decade from 2030-2040, the two waves will become exactly out of synch and this will … Web1 day ago · Solar activity was up for this reporting week, April 6-12.

WebAug 15, 2024 · NASA Heliophysicists have released a revised prediction for Solar Cycle 25. The report generated by Ricky Egeland, a Solar Physicist working in the NASA Space Radiation Analysis Group now calls for the peak of Solar Cycle 25 to top out at a value of 195 ± 17 based upon the new scale for calculating Smoothed SunSpot Number. WebJul 7, 2024 · The strongest one ever recorded was an X28 flare in 2003, hundreds of times more powerful than the July 3 X1.5 solar flare. X10-class and stronger solar flares typically have effects that last for most of a day and affect the entire sunlit side of the Earth. Fortunately, X10-class solar flares occur only about once every 20 years or more.
