Abstract:
'The VERITAS Imaging Air Cherenkov Telescope (IACT) array was augmented in 2019 with high-speed focal plane electronics to allow the use of VERITAS for Stellar Intensity Interferometry (SII) observations. Since January 2019, VSII recorded more than 250 hours of moonlit observations on 39 different bright stars and binary systems ($m_V < 3.4$). The observations resulting in the measurement of the diameters of several stars at an effective optical wavelength of 417 nm with better than 5% resolution. This talk will describe the status of the VSII survey and  analysis.'
