Mu Sgr
Mu Sgr (HD 166937; 'Polis', V=3.85). It is an early B supergiant in a long-period binary (P~180 d) that is possibly eclipsing (the BRITE data should answer that). The C II lines 6578/6583 and Si II 6347/6371 can be used for the binary motion, and the H-alpha profile changes quite a bit from two observations obtained recently. An R > 10k with S/N > 150 would be great if possible and wavelength coverage from 6300-6750 to also cover He I 6678 would be great.
