1 Otero, Sebastian Alberto Chart in 1971RA......8..211M points to the fainter star but the authors identify the variable as the NW component of a close double in the text. UCAC3 data for the individual components (variable, V= 13.54 and companion V= 14.1, sep. 5") and APASS data for the combined brightness (V= 13.03 at maximum with a faint datapoint at V= 13.78) confirm the identification. Range in the table has been corrected.
