Preparing for the 2017 total Eclipse

On 21 August 2017 a total solar eclipse will pass across the continental United States, from Oregon on the west coast to South Carolina on the east. The eclipse will be a phenomenal experience for the millions of people who see it, but it also offers a unique opportunity to conduct scientific research of the solar atmosphere.

Critical Design Review Completed!

Approximating a model’s “true” state by applying Kalman filtering to solar cycles, a technique first developed in the 1950s and 1960s to help Apollo 11 settle safely on the Moon.

Mauna Loa Solar Observatory

The Mauna Loa Solar Observatory 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.

The MLSO Website has a new Gallery Page!

The Mauna Loa Solar Observatory website has a newly revamped Gallery Page to highlight interesting solar events caught by MLSO instrumentation. Each new entry will include a downloadable animated GIF file suitable for insertion into presentation slides!

Sunspots and Photospheric Dynamics

Sunspots are the most prominent manifestations of magnetic field in the visible layers of the solar atmosphere. Their origin is a dynamo process operating in the solar convection zone.

The Community Spectro-polarimetric Analysis Center (CSAC)

CSAC provides a suite of community resource tools for analysis of the precision polarization data for remote sensing of magnetic fields in the outer solar atmosphere.
