1 Otero, Sebastian Alberto Reached a peak of V= 10.9 on JD 2455898 according to AAVSO V-data.
2 Otero, Sebastian Alberto Orbital period not confirmed. Possible V Sge star. SNIa candidate.
3 GCVS Team HDE 310376 (HA 112, 173). Flickering resembles V818 Sco. Variations by 0.2m in 90s were observed. No periodicity was found. Emission lines He II 4686, CIV - NIII 4630 - 4650 and sometimes weak hydrogen absoptions (corresponding to A or B type) are noticeable in the spectrum [R.E.Schild, ApJ 157, 708, 1969.].
