While the current peak in the 11-year cycle of sunspot activity is on the weak side, the Sun might still produce a major storm at any point. The most dangerous storms are most likely during the waning part of the solar cycle, which will unfold later this decade.

A grand solar minimum would slow global warming but not stop it.

New observations of the magnetic field on the Sun are providing an unprecedented glimpse into solar eruptions that have serious impacts on Earth.

University students and faculty soon will have the chance to peer at day-to-day weather through the same lens used by National Weather Service meteorologists. A new version of the NWS’s workhorse graphics software will reach campuses through UCAR’s Unidata program.

To get at driving forces deep within the Sun, new models aim to unify the Sun’s dynamo and the emergence of magnetic flux—two areas that are challenging to model individually, let alone together.
