Solar Radial Velocity Archive

Search the Solar RV Archive

Modern extremely precisŧe radial velocity spectrographs are now being built with the capacity to feed light from the sun into the instrument in order to aid our understanding of the instrumental characteristics and the Doppler noise caused by convective motion on the surface of stars. The NASA-NSF Exoplanet Observational Research (NN-EXPLORE) program and the NASA Exoplanet Science Institute (NExScI) located at the California Institute of Technology are working together to provide the community access to the solar data products from as many instruments as possible. Reduced solar data products from the NEID spectrograph built by the Pennsylvania State University are currently available for download.


  • April 15, 2024 The object search has been updated to include an optional radius for spatial searches. For example when searching for Barnard's Star, enter 162 arcsec in the the radius field. This feature is helpful in finding sources that have very different astrometry between Gaia DR2 and the current version of Gaia (now DR3). If the radius field is left blank, the default spatial search radius is 30 arcsec.
  • The current version of the NEID pipeline is v1.3.0 (see NEID DRP docs and changelog) Data in the archive are currently being reprocessed with this latest version starting with the most recent data in the archive.
  • Use the Advanced Search page if you wish to access rejected files.
