SNA 85 Aa,Ab: Both NACO/SAM and PIONIER resolved the A componnet as a 50mas
pair, which probably corresponds to the 80mas pair detected through Rad1980
occultation (Radick & Lien 1980). The object may further be an SB1
(Gamen et al. 2008, RevMexAA 33, 54) Sna2014
HD 167659 Hilt 730. The 3 speckle observations all indicate a single star, so we
cannot confirm the existence of a companion found by lunar occultation Msn1998a
(Radick & Lien 1980). Rad1980
