Sunspot Activity Running Well Above Forecast in October 2021

The sunspot number for early October is around 50 which is well above the projected value based on the Sep. 10, 2021 forecast by NASA. In fact, the observation is above the 95th percentile forecast. Conservative forecasts for solar cycle 25 project a similar sunspot number at solar maxima in 2024-25 to the past solar peak occurring twice in 2011-12 and 2013-14. However, based on early trends, solar maximum for 2024-25 could be much stronger.

The West will cool-down and impressively so during the medium-range. However, the eastern 2/3 of the U.S. may receive a record warm mid-autumn.
