Images and Spectra of the 2017 Total Solar Eclipse Corona From Our Oregon Site Frontiers in Astronomy and Space Sciences

We report on early results from a suite of instruments for imaging and spectra we deployed to Salem, Oregon, for 2 min of totality at the August 21, 2017, total solar eclipse. Our instruments included refracting telescopes and telephoto lenses for use with CCD detectors and DSLR cameras, narrow-band filters at the wavelengths of coronal emission lines ([Fe XIV] 530.3 nm and [Fe X] 637.4 nm), and spectrographs. We also monitored the effect of the eclipse penumbra and umbra on the terrestrial atmosphere. The total solar eclipse of August 21, 2017, was the first whose totality crossed only United States territory since the origin of the country, and the first to cross the Continental United States from coast to coast in 99 years. As a result, major campaigns of scientific research and of outreach were carried out. 2018 CIRES (Cooperative Institute for Research in Environmental Sciences) NESDIS (National Environmental Satellite, Data, and Information Service) NCEI (National Centers for Environmental Information) Submitted https://doi.org/10.3389/fspas.2018.00037 CC BY 2286
