About the Mauna Loa Solar Observatory

The Mauna Loa Solar Observatory (MLSO) occupies part of the NOAA Mauna Loa research site located on the flank of Mauna Loa at an elevation of 3440 meters on the island of Hawaii. It is operated by the High Altitude Observatory, a division of the National Center for Atmospheric Research, which is located in Boulder, Colorado.

The Physical Origin & Magnetic Sensitivity of the Scattering Polarization Observed in the O I IR Triplet at 777 nm

Response functions to a horizontal 1 G magnetic field of the emergent Q linear scattering polarization
Monday, January 9, 2017

The linearly polarized solar limb spectrum caused by the absorption and scattering of anisotropic radiation has a very rich diagnostic potential, given its sensitivity to the thermal, dynamic and magnetic structure of the solar atmosphere.

Overview and Research Goal

PICS Narrow-band Limb Images

The PICS instrument is now serving images of the limb taken with a narrow-band H-alpha filter. The new data replaces the broad-band images in the MLSO data portal, and its first date of appearance was May 5th, 2009. The animation to the left shows narrow-band limb images of prominence activity occurring at approximately 21:08 UT on May 8th, 2009.
