Two grade 3 orbits. Left: orbit for HIP 19461 = WDS 04100+8042. Half of its 373 yr orbital period has been observed. The components have V magnitudes of 5.59 and 6.30 with spectral types G6 III and A2 V, respectively, and ΣM = 6.92 ± 1.60 M⊙. Right: orbit for HIP 11569 = WDS 02291+6724. Nine-tenths of its 49.0 yr period have been completed. The components have V magnitudes of 4.55 and 8.14 with spectral types A2 V and G7 V, respectively, and ΣM = 2.39 ± 0.24 M⊙.
