4 Hümmerich, Stefan Very crowded area; 2MASS J18044158-2709178 (7'' distance; V= 15.3: (mean value of magnitudes derived from UCAC3 and CMC14)) might be affecting brightness measurements. Range from MACHO: 14.24 - 14.90 (V), 12.60-13.45 (Rc). Vmag from other photometric measurements: 13.94 (derived from CMC14) and 15.60 (UCAC3). 2007BaltA..16...37G gives a possible period of P~2000 d. J-K=1.955 (2MASS).
