Progression of solar cycle 25


We plot here the predictions for the sunspot numbers for solar cycle 25 from the NOAA/NASA/ISES panel and from a paper by McIntosh et al. (2020) . Based on these forecasts, we have calculated the solar storm impact rates at planets and spacecraft. Please see Möstl et al. (2020) for an in-depth description of these predictions. The source code to produce these plots is also available. The sunspot data are taken from the source: WDC-SILSO, Royal Observatory of Belgium, Brussels.
The first two plots are updated daily, the ones below are redone when a new version of our ICME catalog is available.
