1 Otero, Sebastian Alberto Probably constant (some small amplitude variability typical of K2 giants may be present though). The ASAS-3 dataset shows it at V= 10.29 between 2007 and 2009. Data from the literature: V= 10.20; B-V= 1.20 (Fernie et al., 1972ApJ...172..383F) V= 10.22; B-V= 1.23 (Rao, 1980Ap&SS..70..489R) V= 10.29-10.33 in 1994 (CMC,1999) V= 10.31 according to UCAC3 V= 10.29 according to CMC14 V= 10.37 according to Tycho-2 (not trustable at face value) R1= 10.21 in 1999 (NSVS) - No apparent variability. CV= 10.43 in SuperWASP - No apparent variability.
2 GCVS Team According to [T.Cragg, PASP 73, 453, 1961.], type RCB, spectrum R. According to [JRAS Can 67, 101, 1973.], since 1961 is in Max light all the time. According to [M.Ya.Orlov, M.H.Rodriguez, Astron. Tsirk. N813, 1974.], the spectrum is not characteristic of RCB stars. According to [F.Ruemmler, MVS 8, H.4, 63, 1978.], the star was bright near the moments of Min light given in [T.Cragg, PASP 73, 453, 1961.].
