Solar Cycle 25 Prediction Panel

The solar cycle 25 prediction panel an international group of experts co sponsored by nasa and noaa announced that solar minimum occurred in december 2019 marking the start of a new solar cycle.

The first panel convened in 1989 for cycle 22. The panel agreed that cycle 25 will be average in intensity and similar to cycle 24. The solar cycle is important for determining the lifetime of satellites in low earth orbit as the drag on the satellites correlates with the solar cycle especially as represented by f10 7cm. 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.

Additionally the panel concurred that solar minimum between cycles 24 and 25 will occur in april 2020 6 months. If the solar minimum prediction is correct this would make solar cycle 24 the 7 th longest on record 11 4 years. A powerful eruption from the sun s surface on may 1 2013. The current solar cycle cycle 24 is declining and predicted to reach solar minimum the period when the sun is least active late in 2019 or 2020.
