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.

When a geomagnetic storm blasted Earth on January 24, commercial airlines redirected a handful of flights were originally routed to fly over the North Pole. Behind the scenes, NCAR scientists play a role in safety precautions such as these.

Sudden heat-ups of the outer atmosphere are gaining attention for their impacts on communications, but can they be forecast?

A balloon-borne instrument sailing in the Arctic stratosphere in June obtained some of the best observations to date on the high-speed, Sun-driven winds that howl through the thermosphere more than 100 kilometers (60 miles) above Earth.

Alfvén waves contain enough energy to heat the corona and drive the solar wind.
