Just in ... Haleakala FEIS

Final Environmental Impact Statement for the Advanced Technology Solar Telescope on the proposed ATST within the Haleakala High Altitude Observatory (HO) site on Maui was prepared by the National Science Foundation (NSF). The purpose of the project "would be to help scientists understand the solar magnetic activities and variability that drive space weather and the hazards it creates for astronauts and air travelers, and for communications to and from satellites."

Back in May, "Haleakala called best site for telescope" headlined an article in the Star Bulletin that reported NSF had studied 70 sites around the world, including Mauna Kea and Mauna Loa, and selected Haleakala as "the only site that satisfies the goals of the world's largest optical solar telescope."
