Announcing 2024 Boulder Solar Day
Boulder Solar Day is an informal 1-day meeting that brings together researchers from CU, HAO, LASP, NOAA, NSO, NWRA, and SwRI as well as out-of-town visitors to give an overview of solar research being accomplished at local institutes and to discuss current progress on solar instrumentation, observations, and models. Registration, agenda, and abstracts are not yet available.
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.
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?
