The team has prepared by testing equipment aboard the Majestic, a 150-foot yacht belonging to local company Atlantis Cruises. To operate on a swaying boat deck, scientific equipment must be mounted on stabilizing platforms. Weather conditions during the December expedition will also play a major factor in the quality of observations.<\/p>\n<p>During a total solar eclipse, the Sun, Moon and Earth align. It\u2019s a sight that supercharges <abbr>IfA<\/abbr> graduate student, <strong>Sage Constantinou<\/strong>. The upcoming event will mark his third eclipse expedition.<\/p>\n<p>&ldquo;It\u2019s unlike anything you can imagine. The whole sky goes dark, everything gets cold. You wouldn\u2019t think, instantaneously, the air temperature drops,&rdquo; Constantinou said. &ldquo;All the animals in the region just start freaking out, birds, dogs, everything. The sky just lights up with the Sun\u2019s corona.&rdquo;<\/p>\n<h2>How eclipse observations reveal impacts to Earth<\/h2>\n<p>Observations of the awe-inspiring event can help broaden understanding of space weather and enhance <abbr>GPS<\/abbr> and satellite communications. During the <a href=\"https:\/\/www.hawaii.edu\/news\/2021\/07\/13\/double-bubble-solar-eruption\/\">2020 eclipse in Argentina<\/a>, the team discovered a solar eruption that formed a double bubble shape. They observed how it triggered measurable changes in the temperature distribution and density of the Sun\u2019s corona. These events originating on the Sun\u2019s surface can devastate the world\u2019s power grid, and impact astronauts in orbit, so fully understanding their nature is important.<\/p>\n<p>There are many ways to study the solar corona, from spacecraft, to ground-based solar telescopes, but solar eclipses provide a superior opportunity. Even amateur data from consumer-grade cameras can produce scientifically useful imaging. In the past, Habbal and her team have combined their findings with amateur data- however there\u2019s little chance of that this round, given the remoteness of this eclipse.<\/p>\n<p>This research is an example of <abbr title=\"东精影业\">东精影业<\/abbr> M\u0101noa\u2019s goal of <a href=\"https:\/\/manoa.hawaii.edu\/wp\/wp-content\/uploads\/2020\/12\/manoa-2025-strategic-plan.pdf#page=20\">Enhancing Student Success<\/a> (<span class=\"small-text\"><abbr title=\"Portable Document Format\">PDF<\/abbr><\/span>), <a href=\"https:\/\/manoa.hawaii.edu\/wp\/wp-content\/uploads\/2020\/12\/manoa-2025-strategic-plan.pdf#page=25\">Excellence in Research: Advancing the Research and Creative Work Enterprise<\/a> (<span class=\"small-text\"><abbr title=\"Portable Document Format\">PDF<\/abbr><\/span>), two of four goals identified in the <a href=\"https:\/\/manoa.hawaii.edu\/wp\/wp-content\/uploads\/2020\/12\/manoa-2025-strategic-plan.pdf\">2015&#8211;25 Strategic Plan<\/a> (<span class=\"small-text\"><abbr title=\"Portable Document Format\">PDF<\/abbr><\/span>), updated in December 2020.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Shadia Rifai Habbal will lead one of a small handful of scientific teams to carry out observations in the South Pole. <\/p>\n","protected":false},"author":16,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[30,12],"tags":[34,35,1466,1363,9,56],"class_list":["post-152078","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-research","category-video","tag-astronomy","tag-institute-for-astronomy","tag-manoa-enhancing-student-success","tag-manoa-research","tag-uh-manoa","tag-video-2","entry","has-media"],"aioseo_notices":[],"jetpack_featured_media_url":"","_links":{"self":[{"href":"https:\/\/www.hawaii.edu\/news\/wp-json\/wp\/v2\/posts\/152078","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.hawaii.edu\/news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.hawaii.edu\/news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.hawaii.edu\/news\/wp-json\/wp\/v2\/users\/16"}],"replies":[{"embeddable":true,"href":"https:\/\/www.hawaii.edu\/news\/wp-json\/wp\/v2\/comments?post=152078"}],"version-history":[{"count":4,"href":"https:\/\/www.hawaii.edu\/news\/wp-json\/wp\/v2\/posts\/152078\/revisions"}],"predecessor-version":[{"id":152094,"href":"https:\/\/www.hawaii.edu\/news\/wp-json\/wp\/v2\/posts\/152078\/revisions\/152094"}],"wp:attachment":[{"href":"https:\/\/www.hawaii.edu\/news\/wp-json\/wp\/v2\/media?parent=152078"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.hawaii.edu\/news\/wp-json\/wp\/v2\/categories?post=152078"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.hawaii.edu\/news\/wp-json\/wp\/v2\/tags?post=152078"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
