Looking within the min
If the last few years have seen a so-called quiet Sun, its silence has spoken volumes. Researchers have taken advantage of a raft of new sensors and a special observing campaign to learn much about what happens when the sun temporarily powers down.

A new model of the Sun’s open magnetic flux
The solar minimum that bottomed out from 2006 to 2010 was the longest and deepest since modern space observations began. Among other effects, it reorganized the areas of flux from open magnetic field lines that produce solar wind.

Connecting the upper and lower atmosphere
An experimental modeling study by a team of scientists that includes NCAR’s Hanli Liu (High Altitude Observatory) points to the propagation of waves upward from the lower atmosphere as a driver for variability in the ionosphere. The research is an important step toward better understanding space weather.
