Examined the WDS on OΣ 549 (STT). A bit of a mess. A fifth star is noted.
Magnitudes:
A: 6.15 or 6.14 or 4.6
B: 10.34
C: 10.7 or 11.4
D: 10.7 or 11.5
E: 17.2
The 4.6 value comes from the observer LAF from 2005. Very strange.
The latest separations, 2005 up to 2013:
A-B: 192.9
A-CD: 141.9
C-D: 3.1
A-E: 10.2
It's hard to piece all this together. It could be that I saw C and not D on 24 Sep '16. They appear to be about equal brightness and very close together. And getting closer...
