Description:
I found this fairly easily by sweeping over from nu Sco. The magnitude
differential helped to recognize this. Primary is m6.5, secondary m9. Primary
appears to me to be a pale yellow, with the secondary to faint to detect color.
However, seeing wasnt the best; this may affected color. Estimated separation
about 4m.
