Advanced Technology Solar Telescope (ATST) - PLANNED

Sub Type:
Research Areas:
NSF Award:

Advanced Technology Solar Telescope (ATST) Construction under the Major Research Equipment and Facilities Construction (MREFC) Account  (AURA/National Optical Astronomy Observatories)

Research Focus & Anticipated Benefits

ATST will enable study of the magneto-hydrodynamic phenomena in the solar photosphere, chromosphere, and corona. Determining the role of magnetic fields in the outer regions of the Sun is crucial to understanding the solar dynamo, solar variability, and solar activity, including flares and mass eruptions, which can affect civil life on Earth and may have impact on the terrestrial climate. The project is a collaboration of scientists and engineers at more than 20 U.S. and international organizations. 

The telescope will be constructed on the island of Maui, Hawaii. The project is being managed by the National Solar Observatory (NSO). NSO operation and maintenance and ATST design and development are funded by NSF via a cooperative agreement with the Association of Universities for Research in Astronomy, Inc. (AURA).
