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.

Catalogue of MLSO/MK4 White Light Cavities

Determining the state of the corona prior to coronal mass ejections (CMEs) is crucial to understanding and ultimately predicting solar eruptions. A common and compelling feature of CMEs is their three-part morphology as seen in white light observations of a bright expanding loop, followed by a relatively dark cavity, and lastly a bright core associated with an erupting prominence/filament.

Here is a catalogue providing detailed analysis of 98 white light cavities observed by MLSO's Mk4 coronameter:

Lisa Upton

Lisa is a Visiting Scientist here at HAO since September 2014 and also is currently working for Space Systems Research Corporation. In the spring of 2017, Lisa will begin a NSF postdoctoral fellowship at HAO, working as a collaborator with the dynamo group.

Giuliana de Toma

Giuliana de Toma is a Project Scientist in the High Altitude Observatory of NCAR specializing in solar cycle variability and its influence on the corona and heliosphere.

Steve Tomczyk

Dr. Steven Tomczyk is a Senior Scientist and Section Head in the High Altitude Observatory at the National Center for Atmospheric Research. He has spent his career developing instrumentation for the remote sensing of magnetic and velocity fields on the Sun. 

Scott McIntosh

Dr. Scott McIntosh is Observatory Director in the High Altitude Observatory at the National Center for Atmospheric Research. His primary focus of research is chromospheric dynamics and understanding the physical connectivity between the Sun's cool surface and its considerably hotter corona.
