111. Synoptic Q-Maps — Insight into the Topology of the Coronal Magnetic Field

Contributed by Todd Hoeksema. Posted on September 26, 2018

Synoptic Q-maps, which display a geometric parameter describing the squashing factor of elemental flux tubes, are computed using both HMI and MDI magnetic field observations. These maps are useful for understanding coronal configurations relevant to space weather.
