1 Otero, Sebastian Alberto BEST lrcax-567 is identified as 2MASS J18415964+0738102 (18 41 59.65 +07 38 10.2; V~18.5; CR= 16.096; amplitude 0.17 mag.; J-K= 1.10) in 2009AJ....137.3911K. The star 2MASS J18420041+0738050 (18 42 00.41 +07 38 05.1; V= 14.9; J-K= 0.23) which is 13" away shows the same variability but with an amplitude of only 0.03 mag. which proves it is not the variable star. The star 2MASS J18420014+0738074 lies in the middle of the two and its color (J-K= 0.72) is a little bluer than that of 2MASS J18415964+0738102 so it has been identified as the variable. It lies 4.6" to the NW of 2MASS J18420041+0738050 and 8" to the SE of 2MASS J18415964+0738102.
