Coronal solar magnetism

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 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.
