Mauna Loa Solar Observatory (MLSO)
MLSO acquires unique observations of the Sun’s atmosphere to support NCAR’s goal to address critical gaps in understanding the Sun-Earth system and to provide observations to reduce damage and disruption from space weather hazards.
MAUNA LOA OBSERVATORY IS CURRENTLY CLOSED. It closed on Nov 28, 2022 when Mauna Loa erupted. NCAR is working on a solar panel power system to acquire MLSO observations during the April 8, 2024 total solar eclipse. Once a new road is completed in June 2024, additional solar panels will be installed to provide long-term clean power. See the Mauna Loa volcano eruption page.
