Submitted to the National Science Foundation under Cooperative Agreement No. 0946422 and Cooperative Support Agreement No. 1400450 This report is also published on the NSO Web site: http://www.nso.edu The National Solar Observatory is operated by the Association of Universities for Research in Astronomy, Inc. (AURA) under cooperative agreement with the National Science Foundation NATIONAL SOLAR OBSERVATORY MISSION The mission of the National Solar Observatory (NSO) is to provide leadership and excellence in solar physics and related space, geophysical, and astrophysical science research and education by providing access to unique and complementary research facilities as well as innovative programs in research and education and to broaden participation in science. NSO accomplishes this mission by: providing leadership for the development of new ground-based facilities that support the scientific objectives of the solar and space physics community; advancing solar instrumentation in collaboration with university researchers, industry, and other government laboratories; providing background synoptic observations that permit solar investigations from the ground and space to be placed in the context of the variable Sun; providing research opportunities for undergraduate and graduate students, helping develop classroom activities, working with teachers, mentoring high school students, and recruiting underrepresented groups; innovative staff research. RESEARCH OBJECTIVES The broad research goals of NSO are to: o Understand the mechanisms generating solar cycles – Understand mechanisms driving the surface and interior dynamo and the creation and destruction of magnetic fields on both global and local scales. o Understand the coupling between the interior and surface – Understand the coupling between surface and interior processes that lead to irradiance variations and the build-up of solar activity. o Understand the coupling of the surface and the envelope: transient events – Understand the mechanisms of coronal heating, flares, and coronal mass ejections which lead to effects on space weather and the terrestrial atmosphere. o Explore the unknown – Explore fundamental plasma and magnetic field processes on the Sun in both their astrophysical and laboratory context.
