The solar cycle as a research area focuses on the quasi-periodic (~11-year) modulation of solar magnetic activity and its physical drivers, modeling, and impacts. It encompasses the study of dynamo processes in the solar interior, emergence and evolution of magnetic flux, sunspot number variability, and associated phenomena such as flares and coronal mass ejections. Researchers investigate cycle prediction methods, long-term modulation (e.g., grand minima and maxima), and coupling between solar radiative, particulate, and magnetic outputs and the heliosphere, planetary space weather, and climate-relevant upper-atmospheric processes, using observations, theory, and magnetohydrodynamic simulations.
In a teleconference with reporters on Tuesday, representatives from NASA, the National Oceanic and Atmospheric Administration (NOAA), and the international Solar Cycle Prediction Panel announced that the sun has reached its ...

Yesterday the sun released a huge solar flare, and it's heading toward Earth. It's nothing to worry about since it's nowhere near as large as the Carrington Event of 1859, but it is large enough to give us some amazing aurora.
