HAO flew observers to MLSO to observe the Sun during the solar eclipse
On April 8, 2024, the day of the total solar eclipse, HAO observers Ben Berkey (site manager) and Lisa Perez-Gonzalez flew by helicopter to the Mauna Loa Solar Observatory (MLSO) located at 11,200 feet on the north face of Mauna Loa to observe the Sun’s corona using the MLSO coronagraphs. They had to fly to the site since the road and power lines to Mauna Loa were destroyed by a volcanic eruption on Nov 27, 2022. A generator and battery packs supplied the observatory with the necessary power. Unfortunately, clouds prevented observations on April 8, but Ben and Lisa were able to return on April 9 to capture beautiful observations of the corona with both coronagraphs (see images in story).
Chasing the IR Corona through Solar Eclipse Experiments
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.
New Book! The Problem of Coronal Heating: A Rosetta Stone for Electrodynamic Coupling in Cosmic Plasmas
HAO is pleased to announce the publication of a new and timely book written for young and open-minded scientists just prior to the total eclipse over the USA in April. Senior scientist Philip Judge and co-author James A. Ionson ask why, 8 decades after Bengt Edlen published his seminal article, we still do not have a clear answer to one of the longest-lasting puzzles in all of astronomy. Why is the solar corona so hot?
WHPI repository of 2024 Total Solar Eclipse activities
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.
