1 Otero, Sebastian Alberto VSP Note: 13.0 mag. star 6" to the W and 15.3 mag. star 12" to the NNE.
2 GCVS Team VB A (B 14.0m, 5.7", 268deg, 1929). P var. Max II = 2406371 + 486.94d*E (JD2406300 - 25000); Max II = 2426359 + 500.56d*E (JD2426000 - 30500); Max II = 2431377 + 489.0d*E (JD2430500 - 34500); since JD2437600 - see Table. Like R Cen, has a double Max, divided by a comparatively shallow Min II. Max II is usually brighter than Max I. Phase (Min I) = 0.43P, Phase (Max I) = 0.70P, Phase(Min II) = 0.85P.
