Solar Radial Velocity Archive

Search the Solar RV Archive

Modern extremely precise 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.


  • Files flagged for rejection are now hidden from the results table by default. These files may be flagged for low signal-to-noise, a poorly determined wavelength solution, or other data quality issues. Check the "Include files flagged for rejection" checkbox below if you wish to display the rejected files.
  • The EXTSNR value, which is a measure of the signal-to-noise in the extracted spectrum at the wavelength specified in the target submission GUI, is now displayed in the results table.
  • Pyrheliometer data is available here.
