But days before the eclipse, some NASA satellites also enabled scientists to predict what the corona \u2014 the Sun\u2019s outer atmosphere \u2014 would look like during the eclipse, from the ground. In addition to offering a case study to test our predictive abilities, the predictions also enabled some eclipse scientists to choose their study targets in advance.<\/p>\n\n\n\n<p><a href=\"http:\/\/www.predsci.com\/portal\/about.php\" rel=\"noopener\">Predictive Science, Inc<\/a>., San Diego, Calif. \u2014 a private computational physics research company supported by NASA, the National Science Foundation and the Air Force Office of Scientific Research \u2014 used data from NASA\u2019s <a href=\"https:\/\/www.nasa.gov\/mission_pages\/sdo\/overview\/index.html\" rel=\"noopener\">Solar Dynamics Observatory<\/a>, or SDO, to develop an improved numerical model that <a href=\"http:\/\/www.predsci.com\/corona\/aug2017eclipse\/home.php\" rel=\"noopener\">simulated what the corona would look like during the total eclipse<\/a>. Their model uses observations of magnetic fields on the Sun\u2019s surface and requires a wealth of supercomputing resources to predict how the magnetic field shapes the corona over time.  <\/p>\n\n\n\n<p>As the corona and solar material spread outward from the Sun, they can manifest themselves as disturbances in near-Earth space, known as space weather. \u201cSpace weather models must be able to characterize the structure of the corona in order to improve forecasts of the path and possible impacts of these events,\u201d Predictive Science president and scientist Jon Linker said.<\/p>\n\n\n\n<p>One key tool are computer models that simulate events on the Sun before they even happen. This comparing of models and observations is a core aspect of heliophysics \u2014 the field of science dedicated to understanding the Sun and its dynamic influence throughout the solar system. Without the ability to measure the corona directly, heliophysicists test their theories by using complex computer simulations.<\/p>\n\n\n\n<p>Eclipses offer a unique opportunity for scientists to test such models. During the total eclipse, the Moon completely obscured the Sun\u2019s bright face, revealing the innermost part of the corona \u2014 the region where solar eruptions such as coronal mass ejections originate, but is difficult to observe under ordinary circumstances. By comparing their predictions to the observations gathered during the eclipse itself, researchers can assess and improve the performance of their coronal models.<\/p>\n\n\n\n<p>The model the Predictive Science researchers used for their final prediction of the August 2017 eclipse was their most complex yet. In addition to SDO\u2019s maps of the Sun\u2019s magnetic field, it also utilized SDO observations of filaments \u2014 serpentine structures on the Sun\u2019s surface comprised of cool, dense solar material.<\/p>\n\n\n\n<p>Greater complexity demands more computing hours, and each simulation required thousands of processers and took about two days of real time to complete. The research group ran their model on several supercomputers including facilities at the Texas Advanced Computer Center in Austin, Texas; the San Diego Supercomputer Center in California; and the Pleiades supercomputer at the <a rel=\"noopener\" href=\"http:\/\/www.nas.nasa.gov\/\">NASA Advanced Supercomputing<\/a> facility at NASA\u2019s Ames Research Center in Silicon Valley, California.<\/p>\n\n\n<div id=\"\" class=\"hds-media hds-module wp-block-image\"><div class=\"margin-left-auto margin-right-auto nasa-block-align-inline\"><div class=\"hds-media-wrapper margin-left-auto margin-right-auto\"><figure class=\"hds-media-inner hds-cover-wrapper hds-media-ratio-fit \"><a href=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2017\/10\/eclipsecompare2psiaug212.jpg\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1920\" height=\"1080\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2017\/10\/eclipsecompare2psiaug212.jpg?w=1920\" class=\"attachment-2048x2048 size-2048x2048\" alt=\"\" style=\"transform: scale(1); transform-origin: 50% 50%; object-position: 50% 50%; object-fit: cover;\" block_context=\"nasa-block\" srcset=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2017\/10\/eclipsecompare2psiaug212.jpg 1920w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2017\/10\/eclipsecompare2psiaug212.jpg?resize=300,169 300w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2017\/10\/eclipsecompare2psiaug212.jpg?resize=768,432 768w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2017\/10\/eclipsecompare2psiaug212.jpg?resize=1024,576 1024w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2017\/10\/eclipsecompare2psiaug212.jpg?resize=1536,864 1536w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2017\/10\/eclipsecompare2psiaug212.jpg?resize=400,225 400w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2017\/10\/eclipsecompare2psiaug212.jpg?resize=600,338 600w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2017\/10\/eclipsecompare2psiaug212.jpg?resize=900,506 900w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2017\/10\/eclipsecompare2psiaug212.jpg?resize=1200,675 1200w\" sizes=\"(max-width: 1920px) 100vw, 1920px\" loading=\"eager\" \/><\/a><\/figure><\/div><\/div><\/div>\n\n<div id=\"\" class=\"hds-media hds-module wp-block-image\"><div class=\"margin-left-auto margin-right-auto nasa-block-align-inline\"><div class=\"hds-media-wrapper margin-left-auto margin-right-auto\"><figure class=\"hds-media-inner hds-cover-wrapper hds-media-ratio-fit \"><a href=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2017\/10\/eclipsecompare2photoaug212-1.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"1920\" height=\"1080\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2017\/10\/eclipsecompare2photoaug212-1.jpg?w=1920\" class=\"attachment-2048x2048 size-2048x2048\" alt=\"A black circle (the Moon) surrounded by golden streams of light.\" style=\"transform: scale(1); transform-origin: 29% 70%; object-position: 29% 70%; object-fit: cover;\" block_context=\"nasa-block\" srcset=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2017\/10\/eclipsecompare2photoaug212-1.jpg 1920w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2017\/10\/eclipsecompare2photoaug212-1.jpg?resize=300,169 300w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2017\/10\/eclipsecompare2photoaug212-1.jpg?resize=768,432 768w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2017\/10\/eclipsecompare2photoaug212-1.jpg?resize=1024,576 1024w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2017\/10\/eclipsecompare2photoaug212-1.jpg?resize=1536,864 1536w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2017\/10\/eclipsecompare2photoaug212-1.jpg?resize=400,225 400w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2017\/10\/eclipsecompare2photoaug212-1.jpg?resize=600,338 600w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2017\/10\/eclipsecompare2photoaug212-1.jpg?resize=900,506 900w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2017\/10\/eclipsecompare2photoaug212-1.jpg?resize=1200,675 1200w\" sizes=\"(max-width: 1920px) 100vw, 1920px\" \/><\/a><\/figure><figcaption class=\"hds-caption padding-y-2\"><div class=\"hds-caption-text p-sm margin-0\">Predictive Science, Inc. developed a numerical model that simulated what the corona would look like during the Aug. 21, 2017 total solar eclipse.

In times of greater solar activity, the dynamic corona could have evolved too quickly to make such a prediction useful. But in these times nearing solar minimum, both Predictive Science and STEREO\u2019s eclipse predictions offered an opportunity for researchers to improve models and our understanding of the Sun\u2019s current activity.<\/p>\n\n\n\n<p><strong>Related links<\/strong>:<\/p>\n\n\n\n<ul>\n<li><a href=\"http:\/\/www.predsci.com\/corona\/aug2017eclipse\/home.php\" rel=\"noopener\">Predictive Science\u2019s Coronal Prediction for the Total Solar Eclipse<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/www.nasa.gov\/feature\/goddard\/2017\/studying-the-sun-s-atmosphere-with-the-total-solar-eclipse-of-2017\/\" rel=\"noopener\">Studying the Sun\u2019s Atmosphere with the Total Solar Eclipse of 2017<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/www.nasa.gov\/feature\/goddard\/2016\/how-to-read-a-stereo-image\/\" rel=\"noopener\">How to Read a STEREO Image <\/a><\/li>\n<\/ul>\n\n\n\n<p><a href=\"mailto:lina.tran@nasa.gov\"><strong><em>By Lina Tran<\/em><\/strong><\/a><br><strong><em><a href=\"https:\/\/www.nasa.gov\/goddard\">NASA\u2019s Goddard Space Flight Center<\/a>, Greenbelt, Md.<\/em><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>When the total solar eclipse swept across the United States on Aug. 21, 2017, NASA satellites captured a diverse set of images from space.
