Solar Magnetic Fields As Observed By Solis
Abstract
The Vector Spectromagnetograph (VSM), part of the Synoptic Optical Long-term Investigations of the Sun (SOLIS), makes spectropolarimetric observations of the full-disk of the Sun in the photospheric Fe I lines around 630 nm (Stokes I, Q, U and V) and the chromospheric Ca II 854.2 nm (Stokes I and V) line. We present some of the updated SOLIS VSM data products and show how they compare with data from other instruments, e.g., SDO/HMI and Hinode/SP. We also illustrate some of the differences between the photospheric and chromospheric magnetograms, and how they can be used to study the height variation of the magnetic field.
