5 days ago · Each month the solar prediction is updated using historical and the latest month’s observed solar indices to provide estimates for the balance of the current solar cycle and the next.

Oct 15, 2024 · NASA and NOAA track sunspots to determine and predict the progress of the solar cycle — and ultimately, solar activity. Sunspots are cooler regions on the Sun caused by a concentration of magnetic field lines.

Sep 15, 2020 · Scientists use sunspots to track solar cycle progress; the dark blotches on the Sun are associated with solar activity, often as the origins for giant explosions – such as solar flares or coronal mass ejections – which can spew light, energy, and solar material into space.

Mar 28, 2025 · NASA works as a research arm of the nation’s space weather effort. NASA observes the Sun and our space environment constantly with a fleet of spacecraft that study everything from the Sun’s activity to the solar atmosphere, and to the particles and magnetic fields in the space surrounding Earth.

Oct 15, 2024 · Solar activity, such as the storm in May 2024, has led to increased aurora visibility and impacts on satellites and infrastructure in recent months. Listen to the media telecon. Read NASA's article about the news. 1.

Oct 16, 2024 · Now you can join the sunspot count, with the help of NASA’s Sun-watching spacecraft. Choose any of the following activities to track the solar cycle’s progress with sunspots. Images from NASA’s Solar Dynamics Observatory highlight the appearance of the Sun at solar minimum versus solar maximum.

Mar 28, 2025 · NASA observes the Sun and our space environment constantly with a fleet of spacecraft that study everything from the Sun’s activity to the solar atmosphere, and to the particles and magnetic fields in the space surrounding Earth. The Sun emitted a strong solar flare, peaking at 2:27 p.m. EST on Feb. 23, 2025.

Mar 25, 2025 · Solar activity can have effects here on Earth, so scientists closely monitor solar activity every day. An image of active regions on the Sun from NASA’s Solar Dynamics Observatory.

Oct 8, 2024 · When the Sun is most active, space weather events become more frequent. Solar activity, such as the storm in May 2024, has sparked displays of aurora and led to impacts on satellites and infrastructure in recent months. NASA works as a research arm of the nation’s space weather effort.

Jan 6, 2025 · NASA and other international space agencies monitor the Sun 24/7 with a fleet of solar observatories, studying everything from the Sun’s atmosphere to its surface. NASA’s Parker Solar Probe is studying our star from closer than any previous spacecraft.
