Si II 6347 Å in the spectra of UX Ori in 2021 (upper panel) and RR Tau in 2022 (lower panel, left) and in 2021 (lower panel, middle and right) during the brightness minima (red). The dates of the observations and V-band magnitudes are shown in each plot. The blue lines represents the bright state reference SiII line profile. Shown are the observed profiles in the bright states on Feb. 20, 2019, with V = 10.59 mag for UX Ori, and on Jan. 7, 2022, with V = 10.58 mag for RR Tau.
