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 Sun, The Earth, and Near-Earth Space

While solar radiation enables and sustains life on Earth, it also produces “space weather” that can profoundly impact different technologies, including telecommunications, satellite navigation, and the electric power grid.

The neutral winds in the Mesosphere and Lower Thermosphere (MLT) region have been observed at King Sejong Station, Antarctica using a meteor radar and a Fabry-Perot interferometer (FPI) simultaneously.

The Passing of Dr. Peter Fox

Holly Gilbert, HAO director, informed our community of the heartbreaking news of the recent passing of Peter Fox. Peter was at HAO from 1991 to 2008. He was a Scientist until 1995, and Chief Computational Scientist from 1995 to 2008.

Ultra-Fast Kelvin Wave (UFKW) Variations in the Surface Magnetic Field

Kelvin waves are large scale wave that is important for Earth’s atmosphere. The Ultra-Fast Kelvin waves (UFKW) are a subset of the Kelvin waves that can propagate to the mesosphere and lower thermosphere (MLT) ~100km and above due to their high zonal phase speeds.

Magnetic structure of the solar chromosphere-corona transition regions

The bulk of the emission from the plasma called "transition region" plasma originates from structures energetically connected both to the chromosphere and corona.

On single-point inversions of magnetic dipole lines in the corona

Wednesday, March 3, 2021

Prompted by a recent paper by Dima and Schad, we re-consider the problem of inferring magnetic properties of the corona using polarimetric observations of magnetic dipole (M1) lines.

Deciphering Deep-Origin of Active Regions From Analysis Of Magnetograms

Dikpati, et. al., derive magnetic toroids from surface magnetograms by employing a novel optimization method based on Trust Region Reflective algorithm. Toroids obtained are combinations of Fourier modes (amplitudes and phases) with low longitudinal wavenumbers.
