The Mees Dual Coronagraph observes the space above the solar limb
in H-alpha (10,000 degrees) and Fe XIV (2 million degrees). 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 Mees Stokes
video observes the active regions in the H-alpha spectrum line,
formed in the chromosphere at about 10,000 degrees. The field of
view is about 200,000 x 150,000 km. 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 IVM observes a region about 203,000 km
square on the sun.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. The MCCD
normally observes a region about 200,000 km square on the sun. The
Mees White Light Telescope observes the Sun in white light.
