Beta Muscae (R 207) split.
Hi Joe,
Observing note from 25 February 1999 on a night when I rated the seeing at 7/10 (good but not great).
R207 Double star Musca
25cm x363: Brilliant pair but quite close. Split but difficult at x276, no problems at x363. Both are cold white or bluish – close, 1-1.2" in PA 30, only 3/10ths of a magnitude in difference between the components, 3.8 4.1?? Very beautiful. Showpiece.
A measure I saw elsewhere on the net in 2007 was 1.0" in PA 50. Apoastron was in 1954 at about 1.5" and they are currently slowly closing.
Hope that helps.
Best,
L.
