1 Otero, Sebastian Alberto VSP Note: 13.6 mag. star 3" to the SW.
2 Otero, Sebastian Alberto NSVS and AAVSO V magnitudes contaminated by UCAC4 593-082279 (V= 13.6:; sep. 3"). NSVS magnitudes also contaminated by several other nearby stars. Range has been corrected.
3 GCVS Team Slow oscillations are superimposed by rapid ones with A = 0.3m [A.A.Wachmann, Bergd Abh V1, N4, 1966.]. According to [H.Gessner, VSS 7, H.2, 65, 1966.] type EB? Min = 2436659.531 + 0.6990d(:)*E (JD2436600 - 37000) [H.Gessner, VSS 7, H.2, 65, 1966.].
