We present recent progress in the National Institute and Technology (NIST) program to create a catalog of stars with SI-traceable spectral energy distributions known at the sub-percent level. We have constructed and characterized a new spectrograph that is now installed on the NIST telescope on Mt. Hopkins. We have also developed a technique to measure atmospheric extinction along a horizontal line of sight, which allows us to better calibrate our spectrograph using a terrestrial light source as an artificial star.
