As a result, major campaigns of scientific research and of outreach were carried out. 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. We also monitored the effect of the eclipse penumbra and umbra on the terrestrial atmosphere. 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 ( 530.3 nm and 637.4 nm), and spectrographs. 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. 8Enrico Fermi Institute, University of Chicago, Chicago, IL, United States.7Astronomical Institute, Slovak Academy of Sciences, Tatranská Lomnica, Slovakia.6Dexter Southfield School, Brookline, MA, United States.5Icarus Optomechanics, Thessaloniki, Greece.4Cooperative Institute for Research in Environmental Sciences, University of Colorado, NOAA National Centers for Environmental Information, Boulder, CO, United States.3Astronomy Department, Williams College, University of the Andes-Merida, Mérida, Venezuela.2Astronomy Department, Williams College, Williamstown, MA, United States.1Hopkins Observatory, Williams College, Williamstown, MA, United States.Seaton 4, Aris Voulgaris 5, Ron Dantowitz 6, Vojtech Rušin 7 and Thanasis Economou 8 Pasachoff 1 *, Christian Lockwood 2, Erin Meadors 2, Ross Yu 2, Cielo Perez 2, Marcos A.
