ChroMag Optics Testing

The Chromospheric and Prominence Magnetometer (ChroMag) prototype optics under test on a lab bench at HAO. Monochromatic green light is being passed through 88mm of calcite. This is the thickest stage in ChroMag. The fringes are used to test the alignment of the optical elements and the crystal axes. ChroMag is one of the planned suite of three instruments of HAO’s Coronal Magnetism Solar Observatory (COSMO), and will be used for solar physics research and space weather applications.

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.
