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.

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.

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.

CoMP Data Now Available

Coronal Multichannel Polarimeter (CoMP) data are now available from the MLSO data calendar. Expect the number of days with processed data to increase in the coming weeks, so check back often!

The FORWARD Model

The FORWARD model is a suite of IDL and fortran codes that calculates simulated coronal polarization signals from numerical and analytical models of the corona. The images generated by the code are directly comparable to the CoMP data and can be used as guidelines to look for specific magnetic morphologies in the observational data. For more info see the FORWARD Model page.

COronal Multi-channel Polarimeter

The CoMP instrument (see Tomczyk, et al. 2008) can observe the coronal magnetic field with a full FOV in the low corona (~1.03 to 1.5 Rsun), as well as obtain information about the plasma density and motion. Like Solar-C, CoMP records the intensity and the linear and circular polarization (Stokes I,Q,U,V) of the forbidden lines of Fe XIII at 1074.7 nm and also at 1079.8 nm.
