HAO is flying observers to MLSO to observe the Sun during the solar eclipse

HAO plans to observe the Sun’s corona from Mauna Loa Solar Solar Observatory (MLSO) during the total solar eclipse on April 8, 2024, despite the destruction of the access road and power lines to the site. These were destroyed by the volcanic eruption of Mauna Loa on Nov 27, 2022. A generator, 80 solar panels, 24 battery packs, 3 inverters, and associated materials have been helicoptered to the site, which is located at 11,200 feet on Mauna Loa. Funding was provided by the National Science Foundation with work led by NCAR facilities and HAO site manager Ben Berkey.

Astro2020 calls out global coronal magnetic measurements as requiring investment

The recent Decadal Survey in Astronomy and Astrophysics, Pathways to Discovery in Astronomy and Astrophysics for the 2020s stated goals that would be supported by COSMO observations.

COSMO Site and Design Advancement Updates

The National Science Foundation (NSF) has provided funding for the final design of the COSMO Large Coronagraph (LC). At 1.5 meter aperture, the LC will be the world’s largest refractive telescope, and will enable observations of the global coronal magnetic fields.

MLSO Honors the Sun at AstroDay West

On October 6th, the MLSO staff participated in AstroDay 2018, an educational outreach event coordinated by the Mauna Kea Observatories. 3,000 people attended. This was the second occurrence of this event, located in Kailua-Kona, on the west side of Hawaii Island. It featured booths and science displays from various local observatories, robotics clubs from numerous schools, and other tech-savvy groups.

Outreach and Observing at Mauna Loa in Hawaii

Educational outreach is an important and rewarding part of an observer’s job at the Mauna Loa Solar Observatory (MLSO) site located on the flanks of Mauna Loa Mountain at an elevation of 3440 meters in the U.S. state of Hawai’i. MLSO is operated by the High Altitude Observatory (HAO), a division of the National Center for Atmospheric Research, which is located in Boulder, Colorado.

Domes at MLSO

MLSO Facility gets a new dome!

After 50 years of operation, the Mauna Loa Solar Observatory received a major facelift this week. A new dome has been installed at the site. The old dome was removed Tuesday morning, January 5th, and the new dome was installed before the end of the same day.
