SNA 55 Reported as a broad-line fast rotator with line profile variability
(Sana at al. 2008b) and as SB2, we detected two visual companions at Sna2008b
1.1 and 3.4". The 7.3" AB companion reported by Mason et al. (1998) Msn1998a
may lie outside our FOV. See further discussion by Sana et al. (2014) Sna2014
