Solar Cycle 25 Preliminary Forecast
published: Tuesday, June 11, 2019 04:03 UTC

The NOAA/NASA co-chaired international panel to forecast Solar Cycle 25 released a preliminary forecast for Solar Cycle 25 on April 5, 2019. The consensus: Cycle 25 will be similar in size to cycle 24.  It is expected that sunspot maximum will occur no earlier than the year 2023 and no later than 2026 with a minimum peak sunspot number of 95 and a maximum of 130.  In addition, the panel expects the end of Cycle 24 and start of Cycle 25 to occur no earlier than July, 2019, and no later than September, 2020.  The panel hopes to release a final, detailed forecast for Cycle 25 by the end of 2019.  Please read the official NOAA press release describing the international panel's forecast at https://www.weather.gov/news/190504-sun-activity-in-solar-cycle
