Performance and Results from the VERITAS Stellar Intensity Interferometer

The VERITAS Stellar Intensity Interferometer (VSII) has been performing high angular resolution ( \textless 1 mas) observations of bright (MV$=$1-3), hot (O/B/A spectral classification) stars since 2019. For the 2020-2021 observing season, VSII is observing a range of astrophysical targets, including a range of spectral classifications and magnitudes, fast rotators, Cepheid variables, and binary/multiple star systems with short orbital periods (\textless 20 days). The VSII observing program has been designed to provide a catalog of stellar radial measurements of northern hemisphere stars, as well as explore potential sensitivity improvements. In this talk I will describe ongoing improvements to the observatory and new science results associated with VSII observations during 2020 and 2021.
