RZ Psc is an isolated high-latitude post-T Tauri star that demonstrates a UX
Ori-type photometric activity. The star shows very weak spectroscopic
signatures of accretion, but at the same time possesses the unusual footprints
of the wind in Na I D lines. In the present work we investigate new
spectroscopic observations of RZ Psc obtained in 2014 during two observation
runs. We found variable blueshifted absorption components (BACs) in lines of
the other alcali metals, K I 7699 \AA\ and Ca II IR triplet. We also confirmed
the presence of a weak emission component in the Hα line, which allowed
us to estimate the mass accretion rate on the star as M˙≤7⋅10−12Msun yr−1. We could not reveal any clear periodicity in the
appearance of BACs in sodium lines. Nevertheless, the exact coincidence of the
structure and velocities of the Na I D absorptions observed with the interval
of about one year suggests that such a periodicity should exist
