1 Otero, Sebastian Alberto Classified as a T Tauri star (intermediate between WTTS and CTTS) in 1997A&AS..125...11S with a possible period related to rotation. The light curve shows UXOR-like fadings too, so it was classified as such in 1999AJ....118.1043H
2 GCVS Team Common proper motion with AB Aur (P = 3'). Associated with a small bright nebula. OH emission.
