Classified as RS in 2020ATel13593....1J but with a spectral type A5Iab in 1972POAN....2...59S. This is consistent with the high luminosity derived from the Gaia DR2 parallax (MV= -4.4 without any interestellar extinction correction, -5.7 adopting E(B-V) ~0.5. B-V= 0.59. Light curve shape is consistent with RS though. Epoch of maximum given. ASAS-3 and ASAS-SN magnitudes contaminated by 2MASS J18094379-4451150 (V= 14.4; sep. 16"). ASAS-3 magnitudes also contaminated by and 2MASS J18094520-4451518 (V= 14.1; sep. 25"). Range has been corrected. |
