We report optical spectroscopic observations of optical transients ASASSN-19qu/2019klf and ASASSN-19qx/2019knu with the Goodman spectrograph on the Southern Astrophysical Research (SOAR) telescope. The targets were discovered by the All-Sky Automated Survey for Supernovae (ASAS-SN; Shappee et al. 2014). We used SNID (Blondin & Tonry, 2007, ApJ, 666, 1024) to identify the supernova types and phases from the spectra.

(1) The spectrum shows narrow Balmer emission lines at rest-wavelength, resembling SNe IIn.
