Top panel: He i λ5876 lines in three LBVs, η Car, P Cyg, and AG Car are compared to MWC 314. We observe blue-shifted wind absorption beyond 1000 km s-1 in MWC 314. Bottom panel: blue-shifted absorption reveals strong variability below 600 km s-1 (solid thick and thin lines), which we also observe in Hδ.
