Grand Challenge Research on Subauroral Polarization Streams

Joule heating of the ionosphere simulated by the NCAR TIE-GCM

A team from the NCAR High Altitude Observatory, Johns Hopkins University, and Rice University, led by HAO scientist Wenbin Wang, was awarded a prestigious NASA Heliophysics Grand Challenge Research Grant to study the magnetosphere-ionosphere interaction known as subauroral polarization streams.

Solar Maximum Mission Information and Data on the MLSO website

The Solar Maximum Mission (SMM) satellite was launched in 1980 aboard a NASA Delta rocket. Among SMM's primary science objectives was the study of the dynamics of solar flares and the study of solar magnetic fields associated with the flare phenomenon. Towards this end, the High Altitude Observatory (HAO) provided a white-light coronagraph/polarimeter (C/P) to study the relationship of the corona to the flare process.

On the watch for solar superstorms

NCAR solar physicist Scott McIntosh is raising awareness. 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.
