1 Otero, Sebastian Alberto VSP Note: 13.6 Vmag. star 5.6" to the NNW.
2 Otero, Sebastian Alberto Amplitude in BAV Rundbrief, 4/2015, ASAS-3 and APASS data is for the combined magnitude of the variable and UCAC4 585-074142 (V= 13.6; J-K= 0.72) which is 5.6" to the NNW. The new identification is based on 2MASS colors (J-K= 0.39) and CMC15 (V= 14.15) and UCAC3 (V= 14.7) derived magnitudes. Range has been corrected.
