Recent ASAS-SN data are better represented by a longer period of 214.5 d.. There are 10 stars contaminating survey data. A (Gaia DR2 4102779299189483520, V = 18.4; sep. 5"), B (GSC2.3 SA79079246, V = 18.5; sep. 12"), C (Gaia DR2 4102779299189462528, V = 18.9; sep. 13"), D (Gaia DR2 4102779294896205696, V = 17.3; sep. 14"), E (2MASS J18334845-1656160, V = 17.3; sep. 17"), F (2MASS J18334865-1656140, V = 16.4; sep. 19"), G (2MASS J18334664-1656263, V = 18.6; sep. 20"), H (2MASS J18334627-1655570, V = 18.3; sep. 20"), I (2MASS J18334602-1656156, V = 18.3; sep. 21"), J (Gaia DR2 4102779363615686656, V = 18.8; sep. 21") APASS data contaminated by A and B. ASAS-SN data contaminated by A, B, C, D and E. ASAS-3 data contaminated by A, B, C, D, E, F, G, H, I and J. Range has been corrected.
