Coronal Solar Magnetism

Magnetic Nulls and Super-radial Expansion in the Solar Corona

Coronal pseudostreamer magnetic topology
Monday, May 1, 2017

Magnetic fields in the sun's outer atmosphere, the corona, control both solar-wind acceleration and the dynamics of solar eruptions.

DKIST: Solar Physics in Service of Society

Phil Judge, Claire Raftery, Sarah Jaeggli

Philip Judge, Senior Scientist at HAO, Claire Raftery, Director of Education and Outreach at NSO HQ in Boulder, and Sarah Jaeggli, Assistant Astronomer at the NSO's Daniel K Inouye Solar Observatory in Maui were guests on KGNU public radio in Boulder, CO.

Lisa Upton

Lisa is a Visiting Scientist here at HAO since September 2014 and also is currently working for Space Systems Research Corporation. In the spring of 2017, Lisa will begin a NSF postdoctoral fellowship at HAO, working as a collaborator with the dynamo group.

Feng Chen

Feng Chen joined HAO in 2016 as a post doctoral fellow supported by the Advanced Study Program of NCAR.

The Sun: A Pictorial Introduction

The slides in this collection were written By P. Charbonneau and O.R. White–April 18, 1995.

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.

Solar Transients and Space Weather

Overview and Research Goal

CoMP is being deployed

The Coronal Multichannel Polarimeter (CoMP) is being deployed this week!. To make room for this exciting new instrument, PICS had to be decommissioned (see our "PICS Removal Team" to the left) and CHIP had to be moved to another location on the spar. In PICS' place, a Coronado SolarMax60 telescope will be providing Halpha images. Look for upcoming changes to our homepage as these new instruments come online.
