 | | The Haleakala Stokes Polarimeter (HSP) at Mees Solar Observatory on Haleakala, Maui, Hawaii, measures the polarization of an absorption line in the solar spectrum, and uses the polarization data to map the vector magnetic field in the solar photosphere. |
 | | The Imaging Vector Magnetograph (IVM) at Mees Solar Observatory on Haleakala, Maui, Hawaii measures the polarization of an absorption line in the solar spectrum, and uses the polarization data to map the vector magnetic field in the solar photosphere. |
 | | The Mees CCD Imaging Spectrograph (MCCD) at Mees Solar Observatory on Haleakala, Maui, Hawaii records the spectrum of all points in a region, repetitively over time. |
