HAO News

The total solar eclipse on April 8, 2024, was a great opportunity for the team of HAO, NSO, and NOAA scientists and collaborators to travel to a location on the totality path with the goal of running unique science experiments. Using additional telescopes, binoculars, and outreach materials, we were able to capture the eclipse throughout its phases and share our passion with a very excited local crowd.

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.

The Total Solar Eclipse on April 8, 2024 offers ideal conditions for eclipse science, unique opportunities for cross-disciplinary collaborations, and an excellent occasion for public engagement. HAO is leading the effort through the Whole Heliosphere and Planetary Interactions (WHPI) initiative to support the 2024 Total Solar Eclipse by providing a platform for gathering information on ongoing eclipse activities.

The Mauna Loa Solar Observatory Upgraded Coronal Multi-Channel Polarimeter (UCoMP) coronagraph science data (version 1.0.1) have now been released to the community via the Mauna Loa web page.

HAO hosted a booth at the 2023 National Society for Black Physicists meeting in Knoxville, TN. This was a great opportunity for students Marcel Corchado-Albelo and Chandler Jenkins and postdoc Kinfe Teweldebirhan Gebreegzabihar to reach out to the community on behalf of HAO and NCAR. We are grateful for the tremendous support we got from NASA PUNCH Outreach who provided a kit of their engaging tabletop activities (along with a helpful training!).  

On 14 October 2023, a captivating annular eclipse graced the skies from Oregon to Texas in the U.S. It was a privilege to not only witness this celestial spectacle but also engage with a curious audience that included a team of solar physicists from both the High Altitude Observatory at NCAR and the National Solar Observatory. Visiting students and/or voluntary collaborators were also among the spectators.

Breno Raphaldini, Mausumi Dikpati, and Scott W. McIntosh are highlighted in the HMI Science Nuggets. Helioseismic and Magnetic Imager (HMI) magnetic field synoptic maps are used to evaluate the magnetic field structures’ organization and propagation as a function of time and latitude. It is demonstrated that the organization of longitudinal structures observed on synoptic maps is proportional to the level of activity at given latitudes.

HAO director Holly Gilbert comments: "There was great energy around the UCoMP Users Workshop last week, with many visitors coming from around the world to participate. Thanks to those who made it a success, including many early career folks!" The first-ever UCoMP Data User’s Workshop was held the week of August 29 and was a great success. The purpose was to introduce UCoMP to the community and to organize working groups to collaborate on UCoMP first results to be published in a topical issue of Solar Physics.

The upcoming solar eclipses and excitement of COSMO development have us so giddy that we broke into song (literally). We invite you to watch the result!
