1 Otero, Sebastian Alberto VSP Note: 15.4 mag star 8.5" to the SE.
2 Otero, Sebastian Alberto Two stars of similar magnitude 8.5" apart. The finding chart in the original publication (1943BAN.....9..337F) identifies the variable as the blend of the two. Current identification comes from 2000A&A...357..871C which (unlike the GCVS identification up to September 2013) points to the NW component. ASAS-3 and APASS magnitudes are contaminated by the close companion 2MASS J18502325-2739335 (V= 15.4 derived from UCAC3 and CMC14). Range has been corrected.
