FIN 334 A variable, FU CMa.
1989.9336: The system has opened slightly since the last speckle
observation in 1989.3; unfortunately it was last observed in 1966 so
it may be difficult to pin down the time of periastron passage. Hrt1993
Aa,Ab: Docobo & Andrade (2013) derive a dynamical parallax of 2.03 +/-
0.25 mas and component masses 5.51 +/- 2.64 and 5.51 +/- 2.64 Msun
(for spectral type B3V) or 1.01 +/- 0.25 mas, 6.62 +/- 3.28 and 6.62
+/- 3.28 Msun (for B2IV). See paper for extensive notes on system. Doc2013d
