Analyses of solar coronal prominence cavities by an international group of scientists including HAO's Sarah Gibson, Christian Bethge, Giuliana de Toma, Yuhong Fan, HAO visitor Urszula Bak Steslicka and University of Colorado graduate student Don Schmit, has been profiled in a

Sunspots and Photospheric Dynamics

Sunspots are the most prominent manifestations of magnetic field in the visible layers of the solar atmosphere. Their origin is a dynamo process operating in the solar convection zone.

2013 Synoptic Network

Purpose: The workshop is being held to discuss and gather community input on science requirements, capabilities and instrumentation for a next-generation synoptic network of solar observing instruments.
