We report optical spectroscopic observations of the recurrent nova V3890 Sagittarii (ATels #13047, #13050, #13059) on 2019 Aug 30.71 UT. The spectrum was obtained using the HFOSC instrument mounted on the 2m Himalayan Chandra Telescope (HCT) of the Indian Astronomical Observatory, Hanle, in the 380-900 nm wavelength range. The spectrum consists of strong, broad hydrogen Balmer lines, with an average FWZI of ~9500 km/s. The narrower core has an average FWHM of ~2000 km/s. The dominant non-Balmer lines are O I (7774 and 8446), He I (5876, 6678, 7065) and Fe II, with an average FWHM of ~2000 km/s.
We thank the HCT observers for sparing time to carry out the ToO observations.
