The observed and predicted Solar Cycle is depicted in Sunspot Number in the top graph and F10.7cm Radio Flux in the bottom graph. The predicted progression for the current solar cycle (Cycle 25) is given by the magenta line, with associated uncertainties shown …

Daily, monthly and 13-month smoothed sunspot numbers for the past 13 years, and 12-month ahead predictions. Yearly mean and 13-month smoothed monthly sunspot number since 1700. Monthly and 13-month smoothed sunspot numbers over the last 6 cycles.

Nov 22, 2024 · An interactive graph displays sunspot data all the way back to 1750, showing the correlation between the number of sunspots and the solar cycle. Part of NOAA’s Space Weather Prediction Center, learners can zoom in and out of the …

Multi-year forecast of the monthly sunspot number and the monthly F10.7. Predicted values are based on the consensus of the Solar Cycle 24 Prediction Panel. Penticton, B.C., Canada: 10.7cm radio flux values (sfu), Data Files (link is external).

Throughout the solar cycle, the latitude of sunspot regions varies with an interesting pattern. The graph below shows the latitude of all sunspot regions of the last 22 years versus the time (in years). Sunspots are typically confined between -35° south and +35 degrees north latitude.

Apr 4, 2025 · The purpose of the predictions is to provide future statistical estimates of sunspot number, solar radio 10.7 cm flux (F10.7), and the geomagnetic planetary index, Ap, for input to various space environment models.

The chart on this page shows the sunspot numbers since 1749. That's when the extensive recording of solar sunspot activity began. You can zoom in on this plot by selecting a time period that you wish to view.

We plot here, daily updated, the predictions for the sunspot numbers for solar cycle 25, by the NOAA/NASA/ISES panel (from 2019) and from a prediction based on the timing of the so-called terminator event (McIntosh et al. 2020).

Oct 16, 2024 · An interactive graph of sunspot numbers from the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center reveals the up-and-down pattern of sunspot numbers all the way to the beginning of Solar Cycle 1 in the 1750s.
